This apartment is really incredible.
The location is just perfect ; you are just a block away from the Duomo and all the big attractions of the city.
The apartment in itself is even more beautiful than the pictures ; very well decorated, very big, plenty of space, with high ceillings...
I would not hesitate AT ALL to recommend it, and would stay there again in a heartbeat.
The only negative point would be the wifi that is difficult to get in some of the rooms (but works well in the living room and the kitchen).
