Have used Twister a few times in the last 6/7 years or so. Although they can run up to a half hour…read morelate and might need an extra phone call to make sure they remember your appointment, I trust this service and they have been around a long time. They are also not scared of heavy items, but just be sure to tell them exactly what you will be moving.
The best thing about them, or really couriers in general, is that it's so much more efficient than doing it yourself. Why rent a Robbin&W or hassle with trying to book a Sixt truck - going and picking it up and dropping it off yourself, when you can just call Twister and have it done for you, at an incredibly reasonable price, which is often less expensive than renting a truck(!!!). Simply efficient and economical.
Highly recommend.
