I had a very comfortable stay at Paolo & friend's place! the room was exactly as seen online, the area was great, and Paolo's friends were available for communication.
The location was very ideal for me. Five min walk from the Vatican, very close to restaurants and a few Piazzas. However, a far walk from Colosseum, the ruins, some famous churches, but I enjoyed the walks. The bussing is fairly easy in Rome so if need be it is very close to the BnB to get anywhere you need. You can also get bus tickets from the convenient store under the BnB, theres printing, caffe's etc.
All that you need is within this BnB for a fair price :)
