We had an excellent stay at Fulvia's. The place is right among all the important places to see in Rome. We only had to take a cab to the Vatican. We walked everywhere else. The location is very safe and is right near a few restaurants and a cafe right downstairs. A minutes walk to local transportation. You can't beat the location and convenience.
The apartment is perfect for two people. Might be a bit small if you want to spread things around but no complaints. You have to go up a spiral staircase to get to the apartment.
The only small issue we had was that the internet was down during our stay and we had to make other arrangements.
Fulvia was an excellent host. She helped arrange a cab to pick us up from the airport and was highly responsive to any questions we had. I would definitely stay here again on my next visit.
