Martins apartment is wonderful for a stay in Amsterdam. The apartment is great for two, and the patio is lovely! The tram is only two shorts blocks from the apartment and is a great and affordable way to get around the city. Take tram 1 or 17 and you'll always get yourself back to the apartment.
Martin was very helpful and kind before and during our stay. He provided us a bottle of wine and delicious cookies upon check in. He also gave us some helpful tips and directions.
I would definitely stay there again.
