Ruben's place is great! The room is very big and beautiful, and have everything you need. Also the bed is huge and very comfortable.
Ruben let us leave our lugagge before check in and after check out what helped us a lot. He also provided us with everything we needed.
Location is quite good since is not exactly in the centre but you are in a really nice and vibrant area and very close to everything. As a reference, it is about 15 minutes walking to Rijksmuseum through a nice and save area.
I would recommend and I would repeat!
