I stayed with Silvia for an entire 3 months during an internship I did in Rome, so I know her and her home very well. Her home is in a very residential area with good transport links and a pretty large (for rome) shop exactly opposite the building. There are also cafes closeby for breakfast, bars on the road, a pizzeria a few doors down, and a great gelato shop around the corner. The home is a short (~ 4min) walk from furio camillo metro station so its no effort to get around at all. It is also not a far walk from the park with via appia antica in, which I liked to walk to on weekends sometimes.
The home itself is lovely, and filled with interesting art/film stuff, but still not cluttered. The room I stayed in was large and a very nice space, any guest I had always commented on how nice her home was. There is a cleaning lady that comes every wednesday so the space was always clean. I feel like I had a lot of privacy but also the comfort of knowing Silvia would be there to help if I needed anything.
As a host Silvia was great. Very relaxed and respectful, and if you messaged asking for help with something she would get back to you very quickly. For example, when the air conditioning in my room wasn't working and I asked about fixing it as I was having trouble sleeping in the heat, she had someone there to fix it the next day. If there is a problem she will set about fixing it straight away and you can always rely on her. She is great for giving advice on life in Rome, and is just a generally kind peron.
