The neighbourhood is quite nice; it has a daily street market that sells all sorts of goods (and food). As other reviewers mentioned, the apartment is very close to the metro stop.
The room and bathroom are both spacious, very clean and simply lovely! The bed is super comfortable.
If you're feeling hesitant about staying with a family (with kids), don't! Umberta is one of the nicest people I've met; she has a beautiful home and adorable children. You will feel very comfortable and welcome during your stay there...
