Great location--very close to the museum area and tram stops, walkable to many restaurants, cafes, and bars. Pretty young and hip area. Check in was easy and Auke himself helped with carrying one of our suitcases up the stairs for us. Yes, the stairs are steep and narrow, but they aren't the only ones like that we encountered in Amsterdam. The building feels very safe and secure.
The apartment is very spacious with a nice balcony in the back. The bedroom is facing the street so in one of the mornings it was a bit noisy as a store across the street was doing some construction before 8am. Similarly, one of the neighbors were hosting a small dinner party in the back and the moderate noise didn't stop until about 10:30pm.
The apartment has a unique style of decoration and there are many interesting objects around the apartment. On the other hand, we had to be careful so that we don't accidentally knock them down. So perhaps it'd be a problem for young children.
We really appreciate the location and the large space, and actually welcomed the interesting quirks of the apartment, which is part of the fun of Airbnb.
