Mark's studio was exactly as it was described on his page. He was a very welcoming host and even prepared some juice for us (instead of wine, because we don't drink alcohol). We had 2 keys and when we had a question he would reply immedtiately.

The neighborhood was nice and clean and is near the central Amsterdam station. Delicious food venues are around the corner and basically everywhere. From the appartment we could reach everything by foot, but it is also possibe to take the tram.
