Very tidy, spacious, well equipped apartment. Well located, ~10 mins from the city centre by public transport. Not midst the action, but we liked the quiet neighbourghood quite a bit. Lot of shops bakers/supermarkets in the area, often exotic ones, which is just a plus really. I've been a lot in A'dam and this is a very good spot to discover this city. If you come by car, the P+R Zeeburg is also just ~5 minutes away by tram.
We didnt meet in person with Erwin, but communication was as smooth as it can be.
