Federico s appartment is great. We really recommend it.
The location is literally a 2 min walk from il Duomo, the view is simply breath taking, there is air-conditioning, the bed is very comfy.
Couple of thing you should know is that the both is tiny as is the kitchen.
There is a smell in the bathroom that is quite disturbing but that's not the host's fault. And it didn't impact our stay at all.
Also important to notice that it's the last floor without elevator so about 50 ish stairs.
But overall an excellent stay I highly recommend it. And federico is there if you need him to book a restaurant, taxi or car. Very helpful and friendly host and beautiful apartment.
