We stayed at the apartment for 2 nights and it was just perfect. Very easy to reach by public transport (10min by metro from the central station) but close enough to the city centre to walk (which we did every day). Franz and Maria were very welcoming, they gave us some very nice tips about what to visit and made sure we had everything we needed during our stay. The apartment itself is really beautiful, the room is very nice and the bathroom is clean and nicely decorated. Perfect stay for a weekend in Amsterdam!
