We really enjoyed staying at Jaaps place, the room and especially the bed was super cozy and just like described. The bathroom was clean and the shower was really relaxing after a long day of exploring Amsterdam. Also the coffee maschine at the room was pretty cool, furthermore Jaap placed some nice candy like cookies at the table for us. :)
Jaap is a very friendly and forthcoming man. He told us a lot about the history of Amsterdam.
The local area is quiet and has some nice supermarkets and restaurants.
