Valerio is an awesome host. He checked us in personally and gave us lot of tips and information! His place is centrally located. If you can walk a bit, Colosseum is 18 mins away, Vatican museum 35 mins, Pantheon 1 min. You can cover most of the sights by foot. We had our 3 year old with us and we stopped at the apartment in the afternoon for her nap and it worked out well. Definitely would recommend.
