Federico's place is perfectly located in the heart of Palermo. Our communication with him was really good, he responded quickly to our questions and was clear in his explanations. He met us in person at the beginning of the trip and was very nice and welcoming.
The place itself, unfortunately, did not meet our expectations. Although the space is clearly big enough for 2 people, the rooftop terrace enjoyable, and the apartment easily accessible, the flat did not feel properly cleaned when handed over to us which prevented us from feeling comfortable. We were also finding ourselves cold in the evening as the heating system lacked efficiency.
I would expect the host to make improvements to the place before feeling entirely confident in recommending it.
