We met Jacob's son Michael who welcomed us and was very friendly and helpful. He made us feel very comfortable. The apartment was exactly like it is in the photos and extremely clean and big enough for a studio apartment. The location was very good; 15 minutes to the centre by tram/bus and 5 minutes walk to the biggest park in Amsterdam (Vondelpark). The neighborhood is one of the most expensive areas in Amsterdam with nice little cafes. Overall, it was a great experience and I totally recommend Michael and his apartment.
