Amazing location, and the apartment is OH SO NICE. The decoration is amazing, so well furnished, comfortable, and the kitchen is completely equipped. The heater is also very very useful in the winter months. Large windows, too!
My only gripe was that the bathroom tends to stay very cold - and on our first morning we didn't have any hot water (we didn't test it when we arrived, turns out the heater was busted, but Foppe got this fixed very quickly for us).
I loved the location - very close to a supermarket and some nice restaurants, as well as main tram stops and even the bus to the airport stop. VERY Steep stairs to climb, but that's Amsterdam for you.
I wouldn't doubt on staying here again if I have the chance to go back to Amsterdam.
