My husband and I stayed at Sveva's place for our honeymoon in Rome for 8 days.
Sveva was a great host. Her friend let us in on our first day, and he did a great job showing us the features of the apartment and the neighbourhood. Sveva was a great help arranging cars to and from the airport for us.
The apartment is as shown in the photographs. The bathroom could use an update, especially the shower and a dripping tap, but it would not stop me from staying there.
The neighbourhood is fantastic; much more of a local flair than other neighbourhoods I have stayed in, in Rome. There is a bit of street noise from the front door in the living room, but if you close the bedroom door at night you do not hear it. We were in a great spot to walk to all the hot spots in Rome - 10 minutes to Campo di Fiori, 25-30 minutes to the Vatican, 35-40 minutes to the Colleseum; and doing the walks is a great way to see Rome.
There is a small patio off the bedroom that was very cute, with a little table and chairs. We did not use it much, but it is a nice bonus.
I would definitely recommend staying at Sveva's place!
