This is a great location in Rome, about a 10 minute walk to the Cipro Metro station. From there, you can get to Termini Station in 15 minutes. From the Cipro station to the apartment is a 4 Euro Taxi ride. About 5 minutes walk is a 24 hour supermarket which has everything. Also, about 5 minutes walk on the way to the Vatican are numerous restaurants open till midnight which serve great food at a good value. I found the food there generally better than in the tourist areas of Rome.
The apartment is on a busy street, but things quiet down after 10pm so I did not have any problems sleeping. The apartment was immaculate and Valenitna brought fresh towels. It is on the 7th floor but the elevator works fine. I stayed one week.
The shower is 4' x 2' so if you are a big guy like me (6'3) you may feel a bit cramped, but it is perfectly serviceable. This is a great place to stay and I recommend it highly.
