Frank's appartment was an excellent choice for our weekend in Amsterdam. We were welcomed by the host's daughter Tess, who was very friendly and took good care of everything. The location is very good (comfortable walking distance to city center and main sights, also nice restaurants in the close neighbourhood for breakfast and dinner) and the place itself is just as nice as described, with attention to little details (water and tea/coffee provided, umbrellas, map of the city).
Thank you for hosting us, we enjoyed our stay very much and will definitely consider to come back when we plan our next visit to Amsterdam!
