B&B Oasi is a very basic accommodation, run by a very pleasant woman named Olga. While it doesn't provide the full amenities and ambiance of a hotel, the accommodation is more than adequate if you just want a clean, safe place to sleep in a convenient location. It's located very close to Termini Station - the neighborhood is a bit seedy, but the convenience of being a 5 minute walk from the station and the intersection of the two metro lines more than makes up for it. The B&B is located in a classic old apartment block with a courtyard, which I actually found to be very cool. The room was clean and comfortable, the price was very reasonable, and Olga goes out of her way to make her guests feel comfortable.
