We had a wonderfull stay in Enricos flat which is very nice in a modern style. Enrico is a very kind person, always relaxed and gave us several tips how to move in Rome with public transports. He was at home to welcome us and show us the flat, our room and bathroom. We felt comfortable all time. San Lorenzo is the student district with plenty of restaurants, bars and small shops. In the evening a little noisy but we did not care too much. We can recommend both Enrico as host and the flat itself. The period mid/ end of May is great as it wasn't too hot but still sunny.
