We had a very good time at Mark & Andrew's place and it felt really like home there. For 4 weeks we could discover New York and the nice neighborhood and it was absolutely easy and fast to get everywhere by subway (5 minute walk), bus (2 minute walk) or foot.
The apartment is huge, comfy, very good equipped with everything you need and very calm. You also find a well appointed super market nearby and a lovely cafe, which you should definitely check out: Colador Cafe (1000 Bedford Ave).
Mark & Andrew are very nice, helpful and reliable. The communication was easy, we could reach them any time. It was absolutely no problem to store there our luggage when we arrived early in the morning or departed late in the evening.
We loved the apartment and highly recommend it.
