Ellen was a great host during our 2 nights stay in Amsterdam. The house is perfectly located around 20min walk to the center. There are many restaurants around the area and it's very quiet and safe. Ellen was also kind enough to tell us where to eat and go (Im sorry we forgot to return your map).
The studio itself is quite spacious with your own toilet and kitchenette (ref, microwave, kettle, coffee machine, etc). Coffee, tea and some snacks were provided too. All in all both beau and I were very satisfied with our stay.
