I've been to Amsterdam in august in dirk's apartment with my girlfriend Viviana . We found it very nice , bright and spacious . The area is very quiet but full of cafes. And there are also two supermarkets . Twenty minutes walk and you are in Museum Area , thirty minutes and you are in the center of Amsterdam.
Dirk is a fantastic owner , very friendly and accomodating .It took everything he had available
If i went back to Amsterdam would definitely go back to this apartment.
