I spent four days in Rome with a friend and Erica literally made our stay perfect.
She is the perfect host, gave us very useful advice on what else to visit and where to eat. Her apartment is clean, really stylish and in a very good location. It's close to bus or tram stops (and also to Villa Borghese), but sometimes we also walked to the city center.
I can definitely recommend staying with Erica because I couldn't think of a better host and place to stay!
