Gian Lorenzo's place is a gem. What you see on the web is what you get. Spacious rooms, impeccably clean. Great coffee and breakfast too, and an accommodating host. Location of the flat is in a quiet residential neighbourhood surrounded by Celio Villa and parks. The location is easily accessible, however to both Colloseo metro and the San Giovani metro which take you to the central Termini station. If you like a more scenic walk, then take the Colloseo metro. If you want to do a shorter walk, then take the San Giovani metro. The bus stop to San Giovani is a five minute walk from Gialo's home and the bus can take you to the metro in another 5 minutes if no traffic. This takes you direct to most of the touristy areas such as Piazza Espana, Vatican etc, From Termini train station, 10 minute by cab. I will be staying in his place again, certainly.
