I really am unsure how to write this review.... We loved our hosts that were accommodating when our train got a rock on the track and we ended up being 5 hours late and arriving after 11:00pm, but for the price of the apartment felt there were a couple of features that could be upgraded for the money and location.
1. The WIFI works terrible... if you need to do business or pay bills or even look up a place to eat on yelp your out of luck.
2. The hot water in the bathroom would kick on and off spastically, and the bathroom itself was really crammed and kind of old; I don't really mind a little bathroom since it was just my husband and myself but i think the host needs to take out all the cleaning supplies and other things in order to make room bigger if there is ever more guests.
3. IF your into late nights and loud then your good to go; but because the apartment has original windows which gives it charm you can hear the square down below PERFECT, I could even hear the people scanning their tickets to enter into the Duomo! Also the bells ring right at 7am and really go every 15 minutes at times (I loved them but my husband ehhhh not so much).

I guess it all depends on your expectation of what you want your trip to be, I wouldn't say its bad by any means but for the money for the two of us i thought that other Airbnb's we've stayed in all around Europe had more... but its definitely has a beautiful view in the morning when you drink your coffee!
