Awesome location right next to Duomo and the Piazza with many food options. Many of your must see tours are an easy walk (10-15 minutes) from this Hotel. I guess that is what you are paying for. It is way overpriced for what you get at the hotel itself.
The included breakfast is prepackaged stuff that i found to be not edible, except for the yogurt.
As it turns out, the Ambulance parking is right at the plaza itself and that creates a problem for light sleepers like me.
Overall, based on pics,reviews and cost, I expected more; but you can not beat the location
