Laura's place was in the Esquilino district, about 20 minutes walk from Termini where we caught the bus to and from the airport. From her place we basically walked everywhere and only took the metro once to the Vatican. The apartment is actually a studio apartment (what we call in the UK) where the kitchen is joined to the bedroom, but its a cute little fold out kitchen that is so well-equipped you won't need to bring basics like salt, pepper, coffee, tea etc. The bathroom was clean and compact. The bedroom would comfortably fit two. There is a cupboard with a key that you can lock your stuff in. The AC worked well and we were comfy throughout.
There is a supermarket open till late located about 2 min walk from the apartment (super convenient) and a lovely gelato place where you can nip to.
Laura herself greets you to check in and check out, she lives right next door so she is almost always available. She was so kind and responded very quickly to all our queries :)
The only downside is the outside area (can be a bit noisy as it is near the main road, but didn't bother us at all) and its a pretty rough area near Termini. So do watch out for that!
