My wife and I had come to NY for the first time and we had, in simple words, a very pleasant stay.
1. Rosa is a great host and a great person, if you get to see her, she will guide you as a local.
2. House is at great location, nice and quiet, as well as in the vicinity of many restaurants, supermarkets and subway (20-25 mins to Manhattan).
3. Rosa's place is very neat and clean too.
4. There are two shared bathrooms, so chances are you never have to wait, which is really important to me.
5. One of the best benefit staying at her's that she allowed to keep our bag in the hallway, so we could go out and explore. We checked out early, again left our bag in the same hallway and picked it before our flight.
6. Although we were out mostly and only came home to sleep, still it was very comfortable to be around and we felt safe.
Just one small point, the bed would have been a little for comfortable. We were mostly very tired and were able to sleep okay, hence, cannot complain.
I highly recommend Rosa's place and would love to stay again.
