A comfortable apartment, situated in Tor Sapienza, a Roman suburb. I really enjoyed my stay - although people should be aware that the area is not a fashionable one. I never felt unsafe, however. Local shopkeepers are friendly, and there is a supermarket - although it is about a mile away. The apartment overlooks a railway line: you hear trains, but you cannot hear cars. Little noise from neighbours. All the facilities you could want, except for a television. The apartment is on the third floor, and so there are about sixty steps to climb; there is no lift.
The railway station is ten minutes away on foot, and there are plenty of trains during the week. There are fewer on Saturdays, and only three on Sundays - one very early in the morning, then one at 0928, then another in the evening. The railway organisation is a little quirky, but you soon learn how it operates.
I would happily stay in Arianna's apartment again.
