My wife and I rented the room for a long weekend and Antoine was very quick with his responses to any questions we had before we arrived. He welcomed us in the apartment with the keys and a short explanation about the place. That was the only time we've met, though he was always available to answer any question we had very quickly. The room was cosy and nice and the roof was a very fun place to start a day and end a day. The building has a great location near restaurants and bars on Amsterdam and a walking distance from central park. We had a good time and we recommend this place.
