Alessandro was a great host who communicated well and went out of his way to translate into English (we don't speak Italian). He was very responsive, was there when we arrived, and sent local recommendations.
The flat was exactly as per the photos, clean, and linnen provided. It's a great location (you can see the wall of Vatican City from the window), easy to walk everywhere or to the metro. The road is busy which is great and safe, but also means I'd suggest bringing ear plugs if you're a light sleeper.
