If this place is available, then book it! It has everything you need: close to Vatican, public transport (though we managed to walk everywhere around Rome), access to kitchen & washing machine, very comfortable bed, iron, great communication.
It’s on the second floor but it does have lift access if you need it.
Francesco also welcomed us personally for check in, gave us local tips, and allowed us to check out late.
I’ve stayed at many Airbnb’s and this one was one if the best.
