We haven't met Martin in person neither the owner of the apartment but Martin was very helpful throughout our stay and answered via whatsapp very promptly.
The apartment itself is perfect for two people and has a wonderful terrasse on the rooftop. It's easy to explore the city via public transport, supermarket and bakery is directly in the neighbourhood.
Palermo and its restaurants are in walking distance.
We really liked our stay at the apartment and would probably rent it again.
