The appartment is really great and not too far from the center of Amsterdam. I was there with my friends and we loved the beautiful view from the appartment and the quiet neighborhood.
The person who welcomed us, Sol, brought us some food and was very kind. The appartment was clean and corresponds to the photos.
The only negative point maybe was the fire alarm (directly linked to the fire departement) that didn't allow us to cook a lot so we ate oustide most of the time.
However it was a very nice place to stay in Amsterdam and we would love to come back there.
