Great apartment in a really good location between Vatican and Trastavere. Very comfortable beds, and the decor and apartment has a beautiful rustic italian feel. You very much feel like you're in italy when at Paolo's place.
A couple of notes : You do have to be quiet at night, I was up laughing with my friends and got a very solid bang on the walls to tell us to quieten down, fine every night after that but if you're planning a wild one- this isn't the place.
The other note would be that the oven doesn't work, so if you're going from the pictures and buy oven-cook food then you will be disappointed. There's plenty of inexpensive tasty italian food nearby so in fact, you won't need the oven. The hob works and so does the microwave, and there's shops nearby for snacks.
