This was our first experience w/ airbnb and we totally confirm all the good that has been said by the other hosts on Casper and the appartment. Casper was very kind responded quickly to all our questions.
The appartment itself is nice clean and quiet (for NYC) especially the bedroom so we could get a good night sleep. The neighbourhood is ok we didn't feel insecure and the appartment is a 10 minutes walk to union sq from where you can go anywhere in town with the metro lines.
Would definitly recommend to those looking for reliability.
