This apartment is a great choice when visiting Amsterdam! There were a lot of bus/tram stops close by, but we preferred walking - we could get to most of the things we wanted to see easily this way. It was close to the central area, but the apartment itself was very quiet so we had no problem sleeping. Most importantly, it was close to the place where they sell the best apple pie we've ever had (Winkel 43)!
Anne wasn't there when we arrived, but the Stroopwafels she left for us made us feel quite welcomed :) We had no problems contacting her when we had questions and she left helpful notes and maps etc on Amsterdam to help us with our visiting. We would definitely stay there again!
