Francesca is awesome & the space was just as described. You are right in the center of everything and steps from the Trevi.
I would suggest not having a car if you stay here - but we were on a road trip so had one. If you do have one, below are helpful parking areas that locals gave me which was very helpful as parking around here is tough/the garage nearby is 50 a day.
1. piazza della pilotta (we parked here and it was probably 3 minutes from the place! It also cost us 3 euro from 1am- 7pm, it was unreal)
2. via dei santi apostoli (this is another area that was suggested by a waitress)
Fantastic place to stay if you are traveling light & want to be around everything! Also, it was perfectly quiet at night we had no trouble sleeping. We also were able to do some laundry. Grazie Francesca!
