We stayed 2 weeks...great location, comfortable with plenty of space, well equipped modern kitchen and updated bath. Really appreciated the extra bathroom and washing machine. Nice and quiet at night. Antonella was very helpful, offered us extra towels and another set of keys.
It's on the 3rd floor, but in Italy that means 4 floors of stairs, and the stairs are steeper and narrower than usual, so that could be an issue for those with physical disability.
