We booked the room at Sietske place for the long weekend of Easter. It was just as described (even better). The apartment is quite big and has all necessary facilities. The room fits for two. Sietske and Bob were there during our stay. The apartment is close to a Metro and Tram station which can bring you fast to the city centre.
Sietske is an excellent host and went beyond her host responsibilities to make us feel welcome. She and Bob shared with us recommendations for restaurants, bars, places to visit, gave us a lot of tips and show us Amsterdam from a local perspective.
It was a real pleasure staying at Sietske place! And I can only recommend it.
