The check-in was great, we were able to check-in earlier. The people at the reception were super friendly and helpful. We were also able to leave our luggage after check-out and were given a spare key to easily retrieve them. Next to that, the location is really superb. The rooms are at a nice square, at a quite environment in the very center of Palermo.
The huge shared terrace was also very nice, both to read a book at night, as to have breakfast in the morning.
The only drawback was the rather thin walls. We could hear the girls in the neighbouring room which clearly had a lot of fun :D. Also the fan from the neighbouring bathroom was very audible, to a point that it could wake you up. Luckily our neighbours didn't stay up too late, but I can imagine if you have night owls next to you, they could keep you awake if you didn't take a big walk around Palermo like we did.
