We were made very welcome by Frank, even though we had arrived earlier than the 3 pm check in time. Both he and Jacqueline introduced themselves and chatted while they cleaned... Frank gave us his mobile phone number in case we needed it.
The apartment itself was clean and the bed maybe one of the comfiest I have ever slept in.
The only down side I would say is the length of time it took on the subway to get into the city. It suited us but maybe not a group who were in New York for the late nights...
On the positive side, we were a bit wary of the connotations of the Bronx area but never once did we feel unsafe, in fact the majority of the locals went out of their way to be helpful with directions and how to use the subway system etc.
Overall a very pleasant stay, in a very pleasant apartment, in a very pleasant area.
