Valentina's apartment is very comfortable. My wife and I stayed there for a week and it was a pleasurable stay. The location is very nice, 2 minutes from the metro station, 15 mins walk to Piazza del Popolo and from The Vatican. The Building is secure and super quiet.
There are several restaurants close by as well as supermarkets.
The apartment was spacious, it has a nice balcony to enjoy a glass of wine. The bathroom is of a decent size with hot water all the time. The kitchen is simple but has all that you need to cook your own meals.
Valentina was very responsive and responded quickly to any of our queries. Highly recommend this apartment.
