Valter was really kind person and cheerful. He was the great host! The place we stayed was totally enough size for two people and it was ensuite, and it's close to everywhere in Rome by Bus 46 or 64.
We also enjoyed a lot our lunch in the restaurant on the ground floor of the same building, and it is really convenient and full of joys there.
Definitely we'll go back to valter's place when we are in Rome again.
