Gianluca's apartment was perfectly located, just a convenient 10 minute walk from the Colloseum, 15 minute walk from all the top sites, and a block away from the nearest metro stop. We were initially concerned about the busy streets, however the apartment is tucked away so you won't hear any of the noise.
I would definitely come again! The apartment and location were both very comfortable; a short distance from grocery stores, tobacco shop, amazing gelato, and the "King of tiramisu", Pompi. Gianluca is gracious host, always available to answer our needs.
