There had been no problem at all to pick up the keys and find the flat, so that was a good point!
The contact was easy with Shunan and her friend, they answered both of them very quickly to our requests.
Great location (quite close from the L train and the 6) in the heart of East Village, a very nice neighbourhood where "real" people actually live in.
The kitty was nice, there was enough food and everything to take care of her, so no problem about that either.

The only disappointing thing was that the flat was a bit dirty when we arrived (according to my mother...) but as we were there only for sleeping that wasn't such a big deal (according to me!).
