Martijn's place was great!! Leading up to my trip and throughout, Martijn communicated with me, gave clear directions, and recommendations. The location is really great and easy to get to from the airport (quick train and a tram). I recommend getting a travel pass for Amsterdam. We got a 3-day pass for 28 Euros and it was well worth it and made traveling quite simple. We also rented bikes. Martijn provided a recommendation in his welcome booklet in the apartment. I also met the cleaning lady on my way into the apartment my first day and she was very sweet and helpful. I highly recommend this place. I had a great stay.
