Guglielmo was a great host ~ very responsive, very truthful/accurate about his appartment. The neighborhood/location was exceptional ~ literally 300 meters from Saint Peter's Square, and a very quick 12 minute walk to Piazza Navona (for example), 11 minutes to the Metro, 1 minute to a taxi stand. The apartment, too, was great ~ exactly as advertised, AC, comfortable beds, great wifi etc.
