My sister and I stayed at Andrea's appartment for 4 nights. He gave us a very detailed description, so that we quickly found it. We chose his flat because of the strategic situation, since we could explore lots of interesting parts of Rome by walking.
Unfortunately our room had no daylight - I could not figure this out by looking at the pictures, but for the given price I think it is okay for students.
As it is supposed to be a "bed and breakfast" we would have expected a little bit more (there were some fruits and juice/milk) but you should plan to buy additional things!
All in all it's okay if you're exploring Rome most of the time and just come to sleep there :-)
