Cristina is a wonderful host! Her friend Fabiola was waiting for us by the building door at the time we've set to arrive at Rome. Then she showed us the apartment, which was perfectly clean, very well decorated, all linens and towel smelled really good! My wife and mother-in-law loved this place!
The place is perfectly located about 200m from the Vatican Museum entrance, 400m from the subway station.
At first I was a bit annoyed about a 150 euros deposit I was asked to do, wondering if I ever would see it again, but Cristina honored and returned me the bail the day before I left. She even brought an delicious ice cream for my children! And she was very very nice!
This is my number one place I've ever stayed, be it Airbnb or any other Bed and Breakfast!
I had a rented car which costed 20 euros a day or 70 euros a week to park at a near private parking, but I don't recommend driving in Rome (chaotic traffic!).
