Expect a very very comfy bed! So comfy you’ll lay in most days looking out of the floor to ceiling windows at the lovely tree outside! The air conditioning works well although doesn’t quite reach the living space fully which may be an issue if you need to use the sofa bed (maybe provide a fan too?) The shower is great! There are two toilets! It’s plenty of space for 2 people and I can imagine it would be fine for 4. The kitchen was fine, fridge worked well.
The location is perfect! Near a carefore and 20 minutes from a big jumbo. Very close to the subway and lots of restaurants bars and cafes in Palermo. Building feels secure
