The location is dead in the middle of the old city centre; all highlight are easily walkable. We could not imagine a better spot! Still, noise levels at night are at a minimum so you can def catch up on some sleep after discovering beautiful Palermo. You should not mind a hard mattress though..
The apartment is smallish but exactly as shown on the pictures. We travelled with a small baby and there was ample space for all the baby stuff :-)
We spent many afternoons on the roof terrace, where the sun disappears at 3.30pm (in March).
Communication with Daniela was easy and she responds faster then the speed of light.
All in all we highly recommend staying at Daniela's place.
