We had a lovely stay in Patrizio's apartment. It was spacious and clean, and although we only rented one room of an apartment, it was very private and peaceful. San Giovanni is a great central location - a 5 minute metro journey from the central Rome station, and easy walking distance from the Colosseum area. Patrizio is very communicative and helpful - he replied to messages quickly and gave us travel time estimates etc. Fantastic value for such a central location!
