We spent several days at Andy and TJ's place in New York and were very happy with the experience. We did not meet Andy in person, but TJ, who received us upon arrival and was there when we left was very friendly and accommodating. We arrived a little later than expected, which was not a problem. He was easy to communicate with and got back to us immediately whenever we needed to contact him.
The room (and the apartment in general) was very nice and comfortable, as well as conveniently located just north of Central Park with local bus and subway stops very close by. The apartment and building and the area felt safe.
We would recommend staying with Andy and TJ and would stay with them again if we return to NY.
