Nicola's place is just like what he described: steps to the Duomo where everything is. The place is a spacious, clean and very comfortable one bedroom apartment with everything one would need. Whole family of three or four can stay there. Nicola is very nice and would be available to help. The only drawbacks are: no elevator in the building so if you don't want to climb stairs it is not for you, no internet (this is what bothered me most - although I found 2 internet cafes nearby later of my stay), and at night (up to 2 AM or so) it could be extremely noisy as party goers come back from their clubs.

Overall, if you don't need internet and don't mind the noise and the stair climbing, it is perfect.
