Antonio was easy to work with by email and texting, although I never met him personally – a very nice woman met me to let me in and explain things. I was close to an hour late for the agreed check-in time, and when I did arrive she (understandably) seemed rushed for time.
The apartment is spacious and well equipped, and it's in the middle of the most bustling narrow "streets" and authentic area of Rome's Trastevere neighborhood – lots of great restaurants and bars within seconds of the front door of the building. The apartment is on the 2nd floor (Italian) or the 3rd floor (American), with no elevator – just rather narrow circular staircase, which could be rather awkward when walking up or down carrying luggage. Some charming neighborhood views from the windows. At night if the windows are open, some of the "colorful" noise from the area comes into the apartment, but with the windows closed it's quiet and sleep was not at all disturbed.
I was very glad to stay in Antonio's apartment. The neighborhood is interesting and colorful, and the apartment is a charming refuge where I always felt rather comfortable.
