I stayed 10 days in July in Peter' apartment with my two girls, and it was a very nice experience.
The apartment is clean, nicely decorated, very well located (4 lines at 5' walk, 20' max to go to Times Square, small and cheap market close by, ...), and quiet ! Which is very nice in Manhattan !
Peter is a very nice host, ready to help and accomodating. I strongly recommend his apartment !
