We stayed at Siz's apartment for a long weekend, and it was exactly what we were looking for. The place looks even better than the pictures, and the apartment is very nicely decorated. There is a "private" patio in the back, and we were lucky to have some good weather in Amsterdam to hang out in the backyard. The neighborhood is pretty nice (de pijp), with tons of nice bars and restaurants around. The city center is around 35 minutes walking. Would definitely stay again.
