The place was really good. The place was located close to the center. I was even able to walk to the Vatican in a nice walk. However, if you don't feel like walking, you can find tones of bus stops and the tube nearby.
Massimo was really nice. He gave me precise indications to get to the place and was really careful about my well-being during my stay.
The room was big and the bed was comfortable. The house was clean and I didn't find any major problems with it.
