this is an amazing apartment, a large open space on two levels with lots of space and a really funky (in a good way!) remote controlled lighting system.
Access is through a courtyard that also hosts a bar and club which comes alive at night. Oddly you need to get past the bouncers to go through, which actually makes you feel cool as you push through a queue of people trying to get in :-)
good location on the bus route of Via Ostiense, and about 700m from the metro B line (Garbatella). A few places to eat nearby but Testaccio is within walking distance for lots more options. Basilica San Paolo is very close and if you happen to be visiting Roma Tre (University) it's just perfect.
The only cons is that the windows look out directly onto the metro/local trains line, with trains passing quite noisily every few minutes until about midnight and starting early in the morning. If you are a light and early sleeper, close the windows and bring your ear plugs!
