We too are struggling to get accommodation booked in Antalya for this October (2024).
To date I've had about 10 requests either declined or ignored. One host even told me that the owner of the property is a very bad person and they don't want me to be a victim. The property in question has 4.8 rating the most recent visit being November 2023. The majority of places I'm requesting have response rates of 90%+.
I'm aware there are some changes to rental law in Turkey where more stringent measures are being put in place however I'm unsure why these places are stlll being allowed to be shown as available. Should airbnb not be looking into this?
