We had a great stay in Valerio's apartment! The apartment is cozy, with a living room, a very big and comfortable bed, bathroom, kitchen and balcony. It was clean and very well located, in the heart of the historical center of Rome!
Valerio is a great host, communication was easy and he was available to help us when we needed.
From Valerio's place, you can go on foot to many historical places in Rome. Most attractions are in half an hour walking (about 2 or 3 km)!
It is definitely a very good place to stay in the historical part of Rome!
