We stayed at Giangiacomo's home for 5 days. It is in a great location, plenty of restaurants nearby, along with cafes, gelatarias and markets for groceries. We were very close to the metro, and the Vatican. The area is nice, not too loud or crowded at night, and we always felt safe and at home.
The apartment is clean and spacious. The bed was comfortable and the kitchen is well stocked with cooking supplies. We had a little bit of trouble getting the shower to run hot but it does work if you wait long enough for the water to heat.
We would recommend this place to anyone looking for a nice apartment in a great location.
