We stayed in the B&B for one night before traveling south and enjoyed our stay. Anna was very welcoming and we had access to the building and our private room via a set of keys. It's about a 10 minute walk from the colosseum (maybe faster but we just didn't figure it out) and close to many shops / bars around the area. Also close to the Termini train station. Overall a great value, very clean, and private. She's there to make you breakfast in the morning as well!
