Riccardo's place is great. Next to a garden with lots of restaurants, drugstores, etc. in the surroundings. The metro station is just in front of the building, and the location near the Train station is very convenient. Also, the connections with other public transports are great!
The best, just a 15 min walk distance from the Colisseum.
The self check-in is very easy and Riccardo is very attentive, he answers right away the messages. The place is great for short stays and it was very clean. 100% secure recommendation.
