My girlfriend and I came in Rome for a romantic stay and booked Nina's flat for 2 nights. It was a really nice appartment, looking exactly like the pictures, cleaned perfectly, pretty cheap and very well situated. It was perfect for the 2 of us, as we only used it to sleep at night and rest a bit between some visits, but it would also be nice for a 4-people family and some light cooking.
Nina and her son Luigi were very kind. They greeted us perfectly and even gave us some advices for restaurants and things to do in the area.
I would definitely recommend the place ! :)
