Excellent location, great choice if you want to spend all day long in Rome, and only crash at the apartment at night. Within walking distance of most major monuments and sightseeing places.
Expect to constantly bump your head if you are over 175-180 cm tall. Very dark, no natural light at all. Wifi very unreliable. And earplugs are a must, the noise from next door bar is especially loud from 2230-0130.
