Principe Pio
Wasn't overly impressed by this one, although it's probably better if you're travelling with someone - I got the impression I might have been pawned off with an inferior room as I was travelling alone and therefore wan't paying so much for it. The room was comfortable enough, but smaller than the others and hideously decorated. Breakfast was pretty poor, and looked like it had been left out all night. The staff were friendly and it's fine if you just need a base to stay while sightseeing, but I wouldn't return.
