I stayed 5 nights at Federico‘s AirBnB.
It was perfectly organized, well located (3 minutes to central station) and you quickly recognize that Federico really takes care about details like cleanliness, neatness, quality of bed, mattress and pillows. I must admit that I slept as good as in my own bed.
He offers free coffee, water, fresh fruits and daily croissants. On top you can reach out to Federico every time you need guidance in Palermo - He responds very fast.
Bathroom is very clean and modern as well.
I totally can recommend this place while staying in Palermo, you will not regret it!
