The place is perfecty located in west-amsterdam, by far the best area where you actually experience the local life. Very close to the amazing Vondelpark and several tram lines that easily take you to centraal station or the city center. the rooftop is amazing and the apartment is very comfortable. watch out for the steep staircase, you have hand rails on both sides to help you.
I highly recommend this place and Jasper is very helpful and flexible.
