We stayed with Atillo mostly because of the location, which really can’t be beat. We splurged a bit on a nicer place, because we wanted to be central and because it was for a longer stay.
The bed was impossible because the bed frame is super squeaky , so after the first night we put the mattress on the floor which made it better, but we were always sweating on the bottom and cold on top - poor quality duvet etc.
The bathroom was definitely not ideal - sink clogged, some mould on the walls, some grime in the shower, the mirror dirty. Also the water tank does not have enough hot water for 2 people to shower, no matter how quick.
I guess we had certain expectations, seeing that Catania had places starting at 25 euros per night, and we chose a place that was in the 40+ euro range. Would I recommend this place to others? I guess, but with the above warnings.
