Check in was super easy as it is via passcode.
You sleep in a renovated garage, so the isolation is the same for a garage. Air Conditioner cools the room down in no time!
Your are right in the middle of bars restaurants and therefore it is quite busy. At around 12pm it starts to get quieter. But one should really be able to handle noise.
In general everything you want to see in Palermo is walking distance.
PS - the Bed is really comfy!
