Valerio's apartment is an oasis in the heat that is the Roman summer. It accommodated my party of 4 perfectly. The location is a 20-25 minute walk to the colosseum and a 15 minute walk to the nearest subway stop. There is a large supermarket about 10 minutes away for all your other needs. Valerio is extremely responsive and it was easy to sort out logistics with him. Highly recommended place to stay.
