I stayed at Flavio's place while on a work trip. Flavio was a great host and responded promptly to all my messages. He also kindly provided an iron, which was very helpful. The flat was very clean and has everything you need for a comfortable stay. Restaurants and public transport are in a 2 minute walking distance, and you can also walk to major tourist sites such as the Colosseum. For those who might be attending meetings at the FAO - the building is just a 5 minute walk away - very convenient!
