Diego's place was in a great location - after spending all day fighting the crowds in the Vatican or the Coliseum it is very nice to come back to a quiet neighborhood. The metro was nearby and taxis were cheap after the trains shut down. The apartment was clean and the bed was very comfortable - he set up an extra mattress for my friend at the last minute.
As a host, Diego ranks in the top five best I've ever stayed with on airbnb. truly feel like I left Rome with a new friend.
