Joop had organized Jasper to meet us and let us in to the apartment, who was very friendly and helpful.
The apartment is in a nice area, with plenty of cafes nearby, and a small supermarket just up the road.
It's in a perfect location, central to the majority of the tourist attractions in Amsterdam so we were able to walk everywhere.
The apartment itself is very comfortable, the bed and bedding is good, the bathroom is small but serviceable, and the bay windows that open to the street are nice to open up on a sunny afternoon.
Thanks again, Joop.
