The apartment is bright and nicely decorated. It's not that close to the metro, but it didn't bother us since we walk everywhere. It's a 5 minute walk to the vatican, then perhaps 20 minutes to cross the river. Roma S. Pietro is about a 10 minute walk. The apartment has everything we needed for a month long stay. Antonella is very responsive and tried to make our stay as pleasant as possible.
The internet is not cable or fiber, but rather cellular data (you use this hot spot device). There is a limit, which turned out not to be an issue on most days. The speed/reliability was an issue for us on some days as we do work remotely, probably not an issue for most people staying for a few days. When we had problems, Antonella was very kind and offered us a second hotspot device to use and/or the use of her office.
As other reviews mentioned, the apartment could probably use a light sprucing up. But overall, it was a pleasant stay thanks to Antonella.
