Travelling with 3 kids, we needed lots of space and convenience. Anna's house provided it nicely. Very spacious house - 25 minutes walk from the Colosseum and 10 minutes walk from the San Giovanni metro station. Anna provided some food during check in (though it isn't part of the deal) and overall, the pleasantness of our stay contributed in our enjoying Rome so much.
Tip: If you are a walker, you could walk around Rome easily from Anna's home. If you are not a walker, using the San Giovanni metro (10 mins walk) or the bus (from Porto San Giovanni - 7 minutes walking) will get you almost everywhere you need to go.
Thanks for hosting us, Anna, and here is wishing you luck.
Best regards
