If you dont want the noise from the bars and Club's , you should rent Giulia's appartment.
In front of the appartment is the party/eating area, but when you walk Down the alley and into the appartment, you are not desturped by any of the noise.
The appartment is cosy and all you need is there.
After all you are only 30 minuts away from the cathedral (or more as you go by the shopping streets)
Higly recommended
