Sergio was an excellent host: communicative, friendly, and welcoming.
The room itself has a comfortable bed and a decent shower, and overall did a fine job acting as home-base for a week.
The flat is located within a relatively short walk from Termini station in the South East of the city, and while it's relatively well connected for public transport (bring ear plugs if you're a light sleeper as the trams run from the street outside) I found myself walking the twenty-or-so minutes into town most days.
