The customer service is the best thing about the Nadia Hotel-- super friendly and helpful personnel. They will make sure you have anything you need. The Nadia is centrally located and overlooks a beautiful canal. This hotel is SO cozy and charming! Since it is part of a historic building the rooms are small, but they are completely outfitted with everything you need, and the beds are very comfortable. The street outside can be noisy, so you may want a room at the back, but we loved our canal view and wouldn't have traded it for a quieter room. We didn't mind the climb up the narrow stairs (typical of the historic buildings,) because your luggage will be brought up for you. But if you have stair issues you will probably be better off in a modern hotel with an elevator. The breakfast room is delightful and the continental breakfast is very good. The price was the best we could find in Amsterdam. We were SO pleased and highly recommend it.
