I had a long term stay at Emmelina's place as I was in Rome for the entire summer for work. Not only is her apartment greatly situated nearby the metro, it is spacious and provides all the necessary appliance to comfortably live in Rome. Emmelina was always quick to respond to any questions and provided me with OJ, milk, water and few snacks to get me started.
I cannot recommend Emmelina's place enough as it made my Rome experience so much stress free and enjoyable.
