Andrea came and greeted us on our first day - very friendly, and was very responsive to any queries we had. The apartment itself is fantastic; clean, well furnished, all the basic necessities one could want in working condition, with some nice decorative touches (the bathroom tiles are fantastic!). As described, very close to the Colosseum, looking out at the remains of Ludus Magnus, a gladitorial school. While the areas between the Colosseum and Il Vittoriano were quite clogged with tourists this time of year, we were pleasantly surprised to find that just a block behind the apartment in the Celio neighborhood is much quieter, with some nice restaurants that don't feel like tourist traps - and the metro is also a very close walk if you feel the need to escape to the "real" Rome!
