Silvia's place is very clean and centrally-located for our week-long visit to Rome. My son and I were able to get to almost everywhere we wanted to go within 30-45 min (at the very most) using public transportation.
We had small breakfast snacks every day, but the kitchen is too small for my purposes. That's okay, because the food in Rome is fantastic.
Silvia responds very promptly and is extremely helpful. I locked myself out once, and she was able to assist me easily.
Lastly, her instructions were very clear.
