A friend and I stayed here for 3 nights in February. The building is beautiful and the area is easily reachable by public transportation. Communication with Alessia was smooth and although my friend and I arrived at different hours and we both had delays in our arrival, she was very understanding and accommodating.
The room is very big, with high ceilings and nice light. The apartment itself is not a private residence where one shares the space with the owner, but more like a B&B or hostel. It is fit for people who want to visit Rome but want to be left alone. Although there were other guests during our stay there, we did not meet them. I personally only met Alessia in person on the last day when I came to pick up my luggage, which she was very nice to allow me to leave hours after check out. My friend also had to pay a "tourist tax" of 3.50 Eur per night, which is a legal requirement in Rome for hotels but it is not mentioned in the room's description. I did not pay this, as I am a student and was told students are exempt from this.
