It's a comfortable apartment. Clean and cosy. Very well designed, nice kitchen. The neighborhood is perfect, not too noisy not too quiet. Stores, restaurants, pubs are very very closed . A big open-market is there. Very lively place. Downtown by walking is a little bit hard (I love to walk in Amsterdam) but can be done (by bike can be perfect). It's closer to the Botanical garden and the zoo, a very nice area too.
It's 5 minutes walk to the Muiderpoort station from where you can take the train directly to Schiphol Airport or Amsterdam Centraal. Yes the stairs are narrow, but it's so common in Amsterdam that it didn't bothered us.
