We had 2 wonderful nights at Sonja's. Not only the weather was great and we celebrated Queen's day, but the room in the houseboat really matched our expectations. It is a hidden gem, close to the Jordan area and within 10-15 minutes by bike from the city centre. The room is really comfy with very good standard for cooking facilities, bedding and bathroom. You also have the feeling to really be on a boat, but in a very quiet area of Amsterdam. Finally, do not hesitate to explore the North of Amsterdam via the Ferry, you are very close from the new Film museum (the Eye) and typical dutch suburbs and villages by the IJ. Sonja was a very nice host, and offered 2 bikes to borrow for free. We also enjoyed the sun on the dek.
