My husband, brother, and I stayed in Peter and Katja's Little Blue House from 04/10 to 08/10 and it was very nice! The cottage is in their backyard, so you have to walk through 2 doors in their own house to get to the cottage. Their dog Boss was there to greet us when we came inside (he is a very friendly dog). Katja greeted us when we got there and explained a few things about the area, the house, and how to get to the ferry/bus stops. We met Peter later in the evening and he gave us some restaurant recommendations (which, by the way, use their bikes and bike 15 minutes to Pllek at NDSM - food was excellent!). The cottage itself is very nice. The main bed was very comfortable and the bathroom was nice and open. The cottage can get humid if you leave the shower door open or forget to turn the heat down, but overall it was very comfortable. The cottage is a 15-minute bike ride to the NDSM ferry (which runs every 30 minutes to AMS-Centraal) and a 5-minute bike ride to a grocery market. The neighborhood is beautiful and it was nice to bike around and see things outside of touristy Amsterdam. Wonderful stay!
