Overall, I enjoyed my stay at the Rembrandtplein Hotel. It is a small European boutique hotel with 20 rooms overlooking a canal and well located in Central Amsterdam.
The owner, Tiko, and his wife, Elena, are very pleasant. One of the workers, Christina, is also a delight. She deserves a raise :). All of them were attentive, kind and went out of there way to be helpful. They all helped make our stay more enjoyable.
My friend and I stayed in separate rooms on the first floor, which is one narrow flight of stairs up. There is no lift (elevator). The walls are quite thin. My friend commented that she could hear everything I said while we were each in our own rooms and when I walked around my room.
My room with its double bed was relatively small with about 15 inches between the foot of the bed and the wall to pass through when crossing from one side of the room to the other side. So getting around the room was tight.
There is no luggage rack. I put the two sitting chairs front to front to hold my luggage.
The bed was very comfortable. The room was fairly clean and the bathroom, though small, was clean and modern. The towels were changed upon request. This is no soap or shampoo provided. Be sure to bring your own.
Overall, if you don't require much space or can adapt to a small room, I would recommend Rembrandtplein Hotel, primarily for its location and very kind staff.
