I'd like to thank you for your review. Having reviews like yours, so precise and so detailed give another view to those who would like to book. A vision, rightly, different from me (which I can be part of).
I answer only to the two points you have recently reported:
The air conditioning as you say is not present for the maintenance of the frescoes. It is not so hot because it is a building with thick and very ancient ura. Fans are the right compromise in July and August, and then you have the chance to sleep in a place with 400 years of history .. in Italy we say: "it is not for every day";) thank you.
For the ambulance, maybe someone was sick in the street .. I'm more sorry for him, but I can not help it :)
For the noise the historic center lives in the night, maybe a group of guys has passed .. Piazza del Duomo is right behind ..
I also thank you as everyone else to have ALL REVIEWS EXCELLENT ratings that have allowed us to become SUPERHOST !!! See you soon! manuel and bea
