We had a lovely stay in Gabriel's apartment. I stayed with my parents who were sleeping in the main sleeping room and I was sleeping on the convertible sofa which is quite comfy. The apartment is not huge but good for 2, max 3. It's very cosy, right in the center of Amsterdam close to main shopping street and right in the middle of Flowers Market. It's a typical Amsterdam house on the 5th floor with narrow stairs, so it was a bit tricky for going up with luggage and stuff but we managed and got used to them! I would recommend it!
