My sister and I spent a week in Irina's flat. We had our own room and bathroom, and we shared a kitchen with others persons. The place was really nice, calm, safe, and clean. The furniture is exactly as the pictures.
Down the flat there are shops, restaurants, ice cream places ... The subway is 10 mins away and the bus station only one minute. It's really easy to go downtown from the flat.
Irina is a very good host, friendly and it was easy to communicate with her.

I strongly recommend this Irina's flat for a good trip in Roma.
