I always dealt with Isodia, not Michalis (just for clarity - this is the review for Stamatia Studios though).

Isodia met me at the square where the island's only taxi drops off its guests that arrive by plane, and recognised me before I even had the chance to look around. The room was spacious, furnished with a fridge, kitchenette, and en-suite bathroom. Isodia was always available when I needed help or advice, either via messaging through the airbnb site or phone. She made a room available to me when I decided to stay longer (more than happy to extend my stay with her), and helped me find a hotel in Rhodes when I left Kastelorizo.

I would definitely stay with her again if I go back to Kastelorizo.
