His apartment is in the heart of Roma, so you can walk around many historical place. I took the red bus (on-off open bus) but it was waste money, from the apartment you can go to sightseeing spots in 10 minutes.
Our host Luca is really nice gentle man. I asked him the airport sending service and he prepared everything that made me feel comfortable. Most of all, Luca was so kind to keep our luggage until our late flight departure. I must say that Luca was one of the best host and I will choose his apartment again if I could visit Rome again.
