Just a wonderful, first-rate apartment! Beautifully furnished, comfy, everything worked right...etc. Paolo is a great host and a wonderful guy. Right next to the Vatican, which makes the neighborhood pretty touristy, but also very convenient to lots of sites. Metro stop is two blocks away, which is a huge plus.
By the way, just about everything you need is on the same street as the apartment. The restaurants were quite good (from the Tavola Calda on the corner to Fabio's great sandwich/salad place to the sit-down restaurant across the street called Dal Toscana--get reservations!) And the little market on the corner run by a wonderful Bangladeshi fellow by the name of Jewel was a twice-daily stop for us.
Highly recommended.
