We've spent ~2 weeks in Antonio's appartments and enjoyed our stay. Appartments are located right near a subway station so you can get anywhere really quickly. There are several supermarkets around in 2-3 min walk. The sound isolation within the building is not great but all the neighbours were really really silent. Isolation from the outside is better, we've only heard ambulanes' sirens (they are very loud in Rome, but that's location-independent) and occasional road workers, in general it was quiet. Tap water is drinkable but has high hardness. Washing machine is great cause it has a drying function. There is no teapot in the kitchen, we were told that it is a common thing in Italy cause italians prefer to boil water in pots. Antonio himself is a nice, responsive and friendly host and leaves in the same building.
Overall, it was a good stay
