We stayed in Gerald's flat for about a month, it was the perfect experience and we had everything we needed to feel just like home: the apartment is well-equipped, clean and warm during the cold months.
It is located in one of the nicest local areas of Rome (but full of life at night!), you can find lots of restaurants, bars and coffee shops in Pigneto, and it's also well connected to the other parts of the city; very easy to go to Termini by bus or by trenino (that are just 20 meters far away from the flat!)
Gerald is an amazing and easy-going person; he has been extremely available all the time, no matter which would be our questions/requests.
All in all, we are very happy we chose to stay in Gerald's flat, 100% recommend it for longer stays!
