I appreciated a lot Carlo's help and availability before my arrival. I asked many questions and he answered very quickly.
The place is very charming and the arrival and check out procedures are extremely well organised. It is extremely clean.
The only thing that could be improved would be installing some noise reduction carpet in the hallway. The walls are extremely thin too, so ear filters are recommended.
Finally the location is great: 10 minutes walk from a subway station (Lepanto) or from Piazza Navona on the other bank, and less than 5 minutes from the airport SHUTTLE stop.
I will keep a very fond memory of my stay and won't hesitate to book this place again.
