Great location, and great security-3 keys to get into the building/the floor/my room. Fresh fruit was always provided, as was a fridge, microwave, and hot water. As others have said, you can hear most other occupants, but I plugged in headphones and listened to white noise and was just fine. The hosts are very kind, and helpful.
The space is tremendously small, but is an inexpensive place to crash at a great location-minutes from Penn station.
