The place is located a half an hour ride by bus 87 from Taksim to which you can get with the airport Havaist bus.
It is all as advertised, clean, utilitarian with everything needed for a stay.
Ozan Baris is very communicative and helpful with his suggestions and his father is as sweet. When I kept to myself and didn’t have breakfast because I was unwell, he brought me fruit to my room. They are kind and hospitable people, even if I only stayed for a night.
Absolutely recommend staying there.
