Giorgia's place was great. She was very helpful with check-in and having her mom let us in, as our flights were cancelled and changed and our check-in time changed a million times.
The apartment is great, but small. The bathroom has no fan. The balcony is definitely tiny and you shouldn't make any plans for hanging out on it.
All in all, I would totally recommend it. Great price for the space and location. Right next to the Vatican, but not a ton of to do other than that in the neighborhood.
