We didn't meet Cristina but she was very friendly and nice. The check in and check out were easy to do and flexible. The flat is very small but well equipped. It is about 12 minutes from the main metro line and 7-8 minutes to the one of the other lines. Having visited in December, it was very difficult to keep the flat decently warm, we had to choose between noisy air con and freezing. The flat overall is tastefully decorated but sure needs a bit of TLC and some stuff needs fixing or replacing. Ok for a couple of nights but would not have lasted longer.
