Perfetto! Fantastico! :)
Excellent location -- very close to Saint Peter's Basilica, Vatican Museums and many other sights. Very close to underground -- easy get from/to airport, Colosseo, Foro Romano, Piazza di Spagna, Fontana Trevi and many other sights.
Isabella is VERY friendly and hospitable.
The room is big, quiet and comfy, very good air conditioner with outside air feed and oxygenization, very good bathroom. Very clean.
I fantastically enjoyed the stay at Isabella's apartment.
