Elena was a kind, quiet and conscientious host. We had to book her place last minute after our original host fell through the day we arrived in NYC, and she was willing to let us check in a bit early and decompress after a stressful afternoon not knowing if we'd have a place to sleep.
The location is close to the L train and nearby some great bars and restaurants. The neighborhood seems active and safe, full of young people. The specific street the building is on is a little dark and creepy at night, though it was definitely fine for us and would be ok for anyone used to city life.
The unit itself is fantastic - clean, private room with lofted bed, great natural light but thick curtains if you need them. Elena has a flair for design and it shows in the apartment. Two things to note-she rents her living room couch as well so there might be another guest if you stay, and if you are super sensitive to smoke it might be tricky as there is some cig use in the living room. These things did not bother us at all though so we had an absolutely wonderful stay. Highly recommended!
