We had a wonderful stay at Giuseppe's place! He was extremely communicative, responding within minutes to most of my texts. He also recommended an excellent (and ridiculously inexpensive!) restaurant to us which was much appreciated :)
The best thing about the flat is definitely it's location: a two minute walk to the Colosseum. Only things to be wary of are that you do get lights coming in from the courtyard at night, and the shower is a little small. Other than that, a perfect stay!
