The flat is located very central, having everything necessary right in front: public transport, many sights like the Colosseum, shops, cafés, supermarkets and more... There is absolutely nothing to complain about.
The room itself is a bit tiny for two persons. It's hard to manage the space with luggage and all in all it feels like staying in a hostel - if you don't have problems with that, you will have a decent time in Patrizio's clean and well equipped flat.
