Mattia was a great host - his communication was very quick and he helped us with any questions we had. We were a group of 13 and Mattia was very accommodating adding an extra bed in one of the apartments for us. The flats were very near San Giovanni metro station which was ideal for getting around Rome, there are also various bus stops within a 5/10 minute walk. Its about a 40 minute walk into the centre of Rome if you are looking to do the journey on foot but it's a lovely walk through the city. The only recommendation I would have is to upgrade the sofa beds as they were very loud and not the most comfortable. The main bed was good through and the kitchen facilities and bathroom were both lovely and clean.
