We had an awesome time in NYC which was also due to the Agustina's flat. The room is as described and shown in the pictures (possibly even better than that) and has an own bathroom (which was a nice add-on).
The location was spot on for us, super close to the subway and in walking distance to cool areas in brooklyn.
Agustina herself is really nice to talk to and didn't hesitate to help us out with recommendations.
I would definitely recommend her place to anyone visiting NYC!
