I was there 2 days ago and all I can say is that I was very comfortable in Luigi's apartment. First he was very responsive before I arrived to the apartment, the apartment also is super clean, he keeps it very tidy and it's very obvious he cares a lot. Second, the location is really really good. I was 5 days there and the only time I had to take the subway was to go to Vatican City, Colliseum is literally 10 minutes away and you are in a part of the city that I felt was less turisty and more filled with chill but good restaurants and stores. Only thing tho, I always bring a couple of ear buds because people can be noisy, and since there is a bar downstairs that may be the case, but that's totally out of Luigi's control. I will definitely come back here when I return to Rome, it's clean, central, well communicated and safe.
Thanks for hosting me! :)
