The room I stayed in was spacious and functional, and the balcony with French doors is a plus since there's no A/C. However, Palermo is noisy so be sure to bring ear-plugs so you'll have an uninterrupted sleep.
The shared bathroom was never an issue for me, and the kitchen was a nice convenience in the morning and at night. But overall, I would describe the accommodations as being best suited for younger travelers who don't require hotel style comforts and frills.
