Great place, great location, great host! Exceeded our expectations.
The apartment is very spacious, absolutely clean, warm and cozy, you feel like in a 5 stars hotel. Although the apartment is on the first floor of the pedestrian street, the windows are sound proof - very quiet.
Lavinia is very responsive and was so kind, waiting for us in the apartment late evening (we were late to check in). Lavinia is very organized, showed us the rooms, explained about the appliances, recommended places to eat, listed current exhibitions in Rome.

I would definitely stay in this apartment again.
