The apartment was spacious enough for 4 people, located in a great area, not too far from city center, within walking distance to the Vatican, within 5 min walk to Metro station, within short walk to markets, restaurants and other local businesses. Tiziana was very welcoming and gave good advice about the places we intended to visit during our stay and answered most of our questions. She reserved car service for us from and to the airport and left a traditional Italian cake for us in celebration of Easter.
The one concern we had was the location of the apartment on the 1st floor next to 2 car repair shops. The shops were working at night for some reason during most of the work week and we could hear lots of noises below our bedrooms in the middle of the night, like banging and screeching and people talking. Also, it was hot at night and we had to open the window which also added some noise from the outside. This affected our quality of sleep and we were tired during the day for several days until we got used to it. If you are light sleepers, this might also be an issue for you.
Overall, the apartment was clean, modern, comfortable and the host was welcoming and accommodating and we had a good stay in Rome.
