Awww, what a great little place. I have visited New York City dozens of times, stayed in dozens of places, but the sheer convenience of this location might be my best experience ever. It's just a few steps from a subway station. Users and taxis pour by at all hours. Greenwich Village is a block away. Trader Joe's and CVS are a block in the other direction. Coffee places, bars, jazz clubs, all quite close.
You would think it would be loud, but it's quiet. I slept better than I have in months.
It is 'quaint' I suppose ... quite small, and up two flights of stairs. But you really get that Old New York feel, especially at Christmastime. I bet it's super pretty when it snows.
If you are traveling by yourself, and Jocelyn's place is available, just go for it! It might be gone if you hesitate - I bet she has many repeat customers.
