No complaints about Sixt! Easy online booking, they kept the car for 3 hours more after I arrived late, it's pretty cheap (EUR90 for 2 days unlimited mileage A170 Merc).
If I had a small gripe, it's that you don't really know what car you'll get. I signed up for BMW 1-series class, which then turned into a Golf Navi when I added GPS (for only EUR2!!), but it was actually an A-class. Anyway, despite being petrol, it's actually a very nice car to drive, everything works just as you might expect, and it's pretty good on fuel.
Car park beneath the shop is a little bit grim, and the stairs smell of wee - take the lift! read more
