Emilio's apartment is beautiful, clean and well-equipped. Everything is new and decorated with style.
Location is perfect- great neighborhood with real Italian restaurants, bars and shops; metro stop Re di Roma in 2minute walk (we didn't use the bus, but there are some in the area, too); most sights are in walking distance (except maybe Vatican- an hour or so- but we actually walked there too, which we recommend because of all the great shops on the way).
If you have already been to Rome and don't need to go sightseeing, there's plenty of stuff to do in neighborhood.
But the best part was the host, Emilio, who was really kind, fast in replying, prepared for possible questions, ready to suggest anything we asked him...not to mention his decoration of the flat!
We definitely recommend this apartment!
