We've had a great time at Mary's Upper East Side apartment. Contact with her via email went very smoothly and we could even text her if we had any questions. She even shipped us the keys, which made checking in effortless.
The apartment itself was very spacious and clean, and had everything we needed. Some notes with instructions were provided, which was very nice.
All in all we've had a great time, and we will definitely consider staying at Mary's place again!
