Maria Cristina was very prompt in answer my request. She was concerned about the fact the actual location of the apartment is San Giovanni and no Colosseo, what is even better, guys; the location of the apartment is great. There is metro station, bus stop, train station, supermarket... everything. She received in the arranged time, explained me everything. The apartment is clean and new. The only negative point is the walls are very thin. You can hear the noises of the neighbohor beside and I guess they can hear us. It was not a big thing cause I basically just slept in the flat.
I recommend the place.
