Agnes' apartment was an excellent arrangement for my staying in Rome. Agnes was very kind toward me and my parents and was in continued communication with us. The location is unbeatable: the subway is at 7 minutes walking distance (and with that you can go anywhere in Rome), besides the fact that the center of the Eternal City is very close. The place was clean and comfortable. The only oddity I would point out is that the bedroom has a locked door which separate this apartment from another one. Well, depending on the guests on the other side, either guests from both sides of the door—you or them— will have to adjust to the needs of the others (e.g., the first days "on the other side" there was a couple with an infant: now you know what I mean...)
The TV was not working the first day, but Agnes intervened right away to get it fixed. I definitely recommend this Agnes' house to anyone who is looking for a "pied a terre" for Roman excursions.
