I've been in Roma at the end of September with my family, in total we were 5 persons.
We´ve found this house, near The Vatican, that could fit us all, and by the photos it´s seemed a very nice place.
And when we arrived, the house was exactly as we've imagined! Lot´s of light and colors, an old-fashioned style house with modern furnitures.
It was very easy to reach from Ciampino, with a Bus from the airport to Termini, and the 64 bus from Termini to Stazione San Pietro. The house is right in front of the station, so you can't be wrong!
The house is in a very strategic place, you can walk to the Vatican in 10/15 minutes, and the 64 bus that stops right in front of the house could bring you near the most important spots in the center of Rome. Or if you don´t mind walking in 30 min you are pratically in Plaza Navona.
The night is very quite there, no problem with cars passing or crowd noise!
We've had a really great time in the house, all of us felt like at home!
I strongly reccomend you this place if you´re going to visit Rome.
And Daria is a great host, promptly replied to all the questions I had, when we arrived the house was ready for us, and very organized giving us all the information we needed at the moment.
