It was a real pleasure to stay at Gloria's, who is a incredibly kind woman. She told us everything we needed to know to have a good stay in Rome. The apartment is more than well located, (you can go everywhere very easily) and is very clean and provided with everything you need.
We left our car via Brianzo, where there is a very cheap parking at 2mn walk from the apartment.
We absolutely recommend this place.
Thanks again Gloria!
