Mei was most welcoming (she had to cancel an appointment as my flight was late) and helped me upstairs with my luggage, and downloaded Yelp to my iPad, which proved useful.
For the price, I was very satisfied with my room (a good mattress, table and chair, and hangars - everything I needed!) but cooking facilities were minimal; the oven is used as storage space (which could be emptied but too much hassle) and there's no microwave, so cooking is really limited. That said, I didn't go to NY to stay in and cook the whole time!
Mei's flatmate was ideal: out a lot but very friendly, helpful, and kept to herself when in :-)
Mott Street is in a great neighbourhood: lively but quiet, with easy access to subway/buses. It felt safe, with a nice friendly vibe, endless cafes/restaurants, and an Apple store a couple of blocks away, which Mei's flatmate told me about (I urgently needed access to something bigger than my iPad).
The flat is not fancy, as reflected in the price, but if you're a woman on a budget who intends to be out a lot, it'll do very nicely!
