Reinout is a very relaxed host and good company at breakfast. He does his very best to make you feel at home and welcome. The luggage drop off facility is really useful so that you can maximise your time before checking in at 3 p.m.
The central location is excellent which means you can walk easily to all the main tourist areas - a real plus.
I’d say you need to be fit and well to manage the stairs, which are well advertised as being a challenge to negotiate if you’re struggling - Reinout will ( and did ) carry your cases to and from the rooms.
A great place to stay if visiting Amsterdam and the leisurely breakfast is excellent!
