Cristiano's place was a gem! It's located near the train and bus station so finding it was a breeze. They were there promptly for check-in, showed us around the room, provided useful insight on specific methods of transportation to get certain places, a map of the city, and even dinner recommendations. There are only two downsides of this, 1. Location to most historical sites (not Cristianos fault!). It was usually about a 20-25 min walk to any of the major historical sites and not within walking distance of the Vatican. That being said, if you ever found yourself tired, it was pretty easy to navigate the city's transportation methods and being located so close to the main station, it allowed you to take a bus or sub to the main station and you were home quickly. The other downside was the air conditioner struggled a little bit keeping the apartment cool. We were able to combat this by opening the bathroom window in the evenings and keeping the ac on during the day while keeping the bedroom door shut all day. This helped a lot at night.
All in all, this was a wonderful stay, the apartment was beautiful and we would absolutely recommend staying here!
