Modern, spacious, creative, interesting apartment we stayed at just for one night in early April before flying home the next morning. We liked the design use of sliding doors, especially the shower's being sandwiched in between two toilets by two sliding doors. It's near the cool-looking Gasometro and the wonderful Montemartini sculpture museum.
Less than 15 minute walk from the Piramide metro and Ostiense train station (from which you can get a train to the airport without having to go to Termini). This neighborhood would not appeal to some visitors, being neither quaint nor ancient Roman, but we enjoyed it, having already stayed in and loved the next-door neighborhoods of Garbatella and Testaccio. This is a neighborhood for Romans.
It's an 11 minute walk to one of the host's (and our) favorite restaurants in Testaccio, Flavio al Velavevodetto.
There are excellent instructions for the apartment and a very welcome elevator. Alessandra was a great communicator before, during, and after our stay, and her friend and neighbor who let us into the apartment and showed us around was very kind and helpful.
This is exactly the kind of quirky, fun, intriguing place to stay that keeps us using Airbnb in Italy.
