We stayed in Anna's Pollonia studio in August 2019. The studio is really nice, very clean and modern, directly on the sea with a small and cute private beach. The beds are very comfortable and the quality of sleep is high.
It is located in Pollonia, in a very pretty and interesting part of the island. Anna was a truly impeccable and helpful hostess.
Milos is an island that deserves to be visited especially in its wildest areas (and I suggest you rent a quad or a small jeep to enjoy all the more remote beaches) ; I believe that the village of Pollonia is a good point to enjoy the tranquility and comfort in moments of relaxation when returning from the many beaches of the island.
I really recommend Anna's place; impeccable accommodation and hostess..!
