We stayed at Majar's place for 9 nights, and we really enjoyed it.
Majar was really helpful with our questions about transportation, and the stay was in general very pleasant.
Majar's house is only 5 minutes away from Halsey st., which is about 30 minutes of subway ride away from Manhattan, so it's a nice location.

The room looks exactly like the pictures - it was nice and clean.
Majar and his family live downstairs, while the Airbnb-room is placed on the 1. fl., so privacy is no problem. But if you're in the mood, my impression was, that they're nice and welcoming people, who enjoy a good chat.

I would definitely recommend Brownstone Two, if you're going to New York.
