My friends and I spent four nights here on our trip to Amsterdam and greatly enjoyed our experience! There is a locked storage area for luggage that we were able to use upon arrival so we could start exploring the city immediately. Having a quiet place to stay somewhat removed from Central Amsterdam was lovely, and a nearby tram stop (2-minute walk) keeps everything accessible. AC and an elevator were especially appreciated in the summer.
While a little expensive (€17.50 at the time of writing), the breakfast spread is fresh and a good quality. Free fruit in the lobby was a plus!
Note: we stayed in triple rooms (only 2 beds) and were on the fourth floor. An elevator goes to the third floor, so there is one flight of stairs to reach the top floor. Within the triple, the AC did not keep the upper level very cool, but opening a window during the day helped.
