We stayed at Franks House for a weekend. It was totally perfect. Everything is in walking distance, you don't even need a ticket for the tram. I recommend to walk, because in this way you see so many different corners of Amsterdam. We arrived late, but this wasn't any problem at all. Frank provided waffles, tea and coffee in the room and gave us a map, which helped to get around Amsterdam. The room was clean and nice. We definitely come back!
