I have hired cars from many companies in various countries. By far I would class SixT as one of the best. The guys in the office were extremely friendly and helpful. I got a car that was far superior to the one I booked. Almost new. Quick look over to check for any blemishes, of which there were none. We were off within 30 minutes of arrival. On return the car was checked and that was it. Perfect. No complaints. Good price in comparison to other sites. I'll use them again. The only one drawback, if it is??? The office is across the main road from the airport and could be a hassle if you have cases. Other hire companies are within the airport building. read more

Do not use this company they are not wife out of £600 by the Belfast City Airport branch My wife was given a free upgrade by an over friendly member of staff. But when she returned the car the same exact same guy was all over the car like a rash. Acting like he was all suprised at the tiniest dent appeared. My wife was in bits having just visited her sick mother in the nursing home. I then tried to speak to the sixt staff member who over the phone he became very defensive and put the phone down on me. DO NOT USE THIS COMPANY THEY ARE SCAMMERS!!!! read more

Terrible company. Lots of hidden charges. Yes it's cheaper online only because you will be hit with hidden charges. They also have one of the worst customers service I've had with car rental. I checked over the phone policy on travel to England and English isle told I would need written permission and extra charge. Payed and on picking the car told that they don't do that but my payment was non refundable. So either take the car u can't use as intended or lose al Ur money. Absolute cheats. read more

Dreadful experience - I booked a car online and booked a premium sedan. On arriving at the hire centre, the Sixt operative processed my payment. It came to well over £300 for a 4 day hire. The operative then showed me the car that he was giving me which was a basic model. I immediately queried and he said that a basic model had been booked on his system. I then showed him the email confirmation which clearly stated Premium Sedan. At this point he became disinterested and quite rude and offered to give me a better car once one came in. He was unable to confirm when this might be and then offered a cancellation. I think he knew exactly what he was doing because the charges were equivalent to that of a Premium Saddam and not a basic model. Overall a very poor service, not made any better by quite a rude approach. I now have to wait for a refund onto my credit card which apparently will take three or four days. If this doesn't happen I will then have to go through my credit card company for a chargeback. Terrible terrible terrible service. I'm from Northern Ireland but dread thinking is this how we treat visitors coming into Northern Ireland from abroad? The experience could've been a whole lot better if the operative had simply pointed out that this was the only car available at the outset and apologised before he started processing the payments. I would then have had a choice and probably would've gone elsewhere as I needed a larger car for the weekend. Take note customer service. read more

I am and have been hiring a car for a few days every month at Belfast International Airport to visit an elderly relative . I have been using Hertz, Budget, Avis ... always without any hassle. On this occasion I thought I try Sixt; never again! Despite the airline been comfortable with my UK driving license as ID, they insisted on seeing my UK passport, which is not required for internal UK air travel. Credit cards etc were deemed insufficient. As I did not have it, my car was not released and my money not refunded. Appalling inflexibility and poor service. AVOID AT ALL COSTS, AS NOT WORTH IT. read more

Atrocious service. There's no shuttle service so be prepared to walk in the rain with luggage to the office. And also to stand outside as only 1 in at a time. Also read the T&Cs carefully as apparently each Sixt region has entirely different policies on payment methods despite being the same company - was offered the facility to use the method I've used time and again with the company for 'just a small amount extra' of over £150 (total rental was less than £100). Have been using Sixt for business for years and in lots of other regions without any problem, but certainly won't be returning. read more

I travel to NI about 3-4 times a year, and rent at Belfast International each time. This was my first time using Sixt. At collection of the vehicle I was treated exceptionally poorly by the colleague I spoke to, was forced to pay excessive charges which are neither stipulated or supported by the terms and conditions, and in the end could only be served by the manager as the colleague had by this stage decided my only alternative was to go to another rental agency and wouldn't serve me. I had paid in advance, and with the reduced excess amount included. At the counter I presented my multiple forms of identification, but the employee would not accept the use of my credit card via Apple Pay. He further refused to accept a credit card in the name of the other named driver, citing it could only be me who paid, and on the original card, using a pin code. He insisted that I pay an additional £110 on top of my original booking doubling it) and when I told him this was excessive he told me I was welcome to go to another rental agency. When the manager finally intervened and served me I was told there were none of my class of vehicle available, I was offered a higher grade. When I asked if I could simply have a smaller car and pay less he told me this would count as a new rental, and I'd have to pay in full again. Found out afterwards I was also charged in Euros, and so had an exchange fee added to convert to Sterling! Given this agency is outside the terminal building, you have to cross a busy road to get to the building, the staff are poorly trained, and they want to charge you far anything they think they can get away with, I'd recommend you rent with a Enterprise, or Europecar, who are inside the terminal building, and were incredibly helpful the each time I rented from them. read more

2 stars for the gentleman who checked us in. They were pretty short-handed but he was very accommodating and helpfully explained how we wouldn't be able to rely on our phones to navigate around Ireland the way we'd been planning. Nothing but good things to say about him. However, -3 stars for the people who answered the phone at the office while we were on the road. We'd arranged to deliver our car to a different Sixt location but while we were travelling discovered that the address of the other office wasn't on our rental paperwork. Not being from Ireland I called the original office for help. The extremely rude young lady who answered the phone claimed not to know where any of the other offices were, told me she didn't have anything listing their other offices, and claimed that the computer she was sitting in front of didn't have access to the internet or any kind of company directory where she might be able to find that information. I'd have looked it up myself but being that we were in very rural Ireland with no data service (which I explained to her), we were unable. She effectively left us to fend for ourselves, and all but told us to get stuffed because she was too busy doing whatever you do in a tiny office with no internet. Completely unacceptable attitude, and I feel bad for the fella that originally helped us as he's probably the only one there trying to do a good job. read more

Man I wish I read the reviews ahead of time before renting from sixt. They don't cover road side assistance (at least in Ireland... Not sure about uk) So in the case of your car getting a flat or a bumper to bumper where you are unable to drive, they let you pay for the fee for rescue. Rent from someone else who offers road side assistance insurance!!!! Zero stars. And this was after they convinced me to use their insurance that would cover EVERYTHING... Everything. Even after asking road side assistance what is covered they simply say "we don't know" and they don't warn you about the fact that they don't refund you for road side assistance for a flat tire, no warning at all or I would have fixed with the spare myself. Nope. Never ever EVER again. Travelers beware!!!!! read more

High quality quick and easy service! I made a last minute booking and got a Skoda Fabia. The prices are very competitive especially for the standard of vehicle. We were able to take the car all round the south of Ireland. I've used this company multiple times now and service is consistently exceptional! read more

Avoid! I wish I had read some of the independent reviews before using them for a family trip. If you think you are getting a deal, its just to suck you in, then rip you off. They are the only hire car company to remove the diagram on your paperwork showing the damage areas - Its not for an honest reason. The written description will be close enough to satisfy you, but when you return the car out comes a diagram on a tablet that "proves" new damage. If you want to spoil your holiday then give these jokers a chance to oblige you... read more

Well i've given them a couple of months to explain but here goes. Avoid Sixt Belfast like the plague, a bunch of crooks. Returned our car and they noticed a small scratch on the hubcap. I dispute responsibility but not much i can do. Much worse though is the disgusting bill for £250 to repair when the hubcap itself would cost £50 to replace. Outrageous crooked behaviour, would never recommend them to anyone. read more
