Elle's place was conveniently located and affordable, but overall was a bit disappointing. Check in was convenient and easy - and yes, it's up three flights of stairs, welcome to New York. I didn't really see the host, but she was friendly and nice the few things we said to each other.
The bed was extremely comfortable, but the room is essentially just that - the bed. Shared bathroom was fine - hot water, towels, etc. However the rest of the apartment was pretty messy and looked like it hadn't been cleaned in a while. It was fine for one night, but there's really no common space. If you're just there to sleep, it's great. Anything else, I'd look elsewhere.
