Dario is very responsible and responsive host. Flat is clean and spacious. You will find everything you need to stay for couple of days.
Apartment is right to the supermarket. Also there cafeteria on the opposite side where you can get morning coffee or buy transport tickets at any time of day. Also Auchan is not far away from there.
There couple of restaurants and small pizza restaurant in the area. Dario will help with suggestions.
Please note, public transport in Rome is quite developed. You can reach any place. I suggest to buy daily or 2 days tickets. With google maps application suggestions you won’t need any other transport. The schedule isn’t accurate but if you patient enough you’ll be regarded.
To get to the Rome historic places you’ll need at least one transport change.
Cheers
