This was a wonderful stay. Room 1 had a lovely view over the rooftops and Hans added many small touches that made the stay better from a bottle of wine in the room, breakfast in the morning, discounts on a couple local attractions, toiletries in case you forgot something and he even guided us on a bike ride showing some parts of the city we would not have seen otherwise then let us use the bikes the rest of our stay.
The only downside, which is standard in most of Amsterdam except very new places, was a narrow steep staircase with no elevator. Even with this I would stay here again.
