Cyn's apartment is big, stylish and well-furnished. There weren't any other guests in the apartment, so it would most likely be just Cyn and you; but Cyn's room is at the other end of the apartment, so you'll have plenty of privacy! Most of the time we had the whole place to ourselves and enjoyed her living/dining room, which is spacious, and very well-lit, thanks to windows all along 2 walls.
Cyn was very hospitable and super nice- gave us tips about traveling and sight-seeing. The subway station is really close too. I would very much recommend her place and her as a host!
