The apartment is ideally located, especially for half-an-hour connections to the Fiumicino Airport. Also, it is close to the ancient part of Rome and is well connected to the metro and bus network.
The surroundings look a bit sketchy (during our stay, my mom was approached and by a drunk woman on the street), but generally you shouldn't worry about it.
The apartment is very spacious and gets a lot of sunlight (the pictures are accurate). The only problems we had were with the water pressure and with the slight odor. They were definitely not a dealbreaker for us, but worth mentioning.
All in all, I would definitely recommend Emiliano's apartment for a short stay in Rome.
