never been to mardin before but I know that turkish people are always very welcoming MashaAllah and that the south east has an interesting climate ...it can be very hot in the summer, Mardin is city that is known for its amazing old architectures and the city is kinda a mix with arab/turkish/kurdish cultures and people from different religions.
mashallah,if a mixture of Kurdish and Turkish ppl reside there then trust me you won’t be disappointed because they'll feed ya .....feed ya delicious food until you explode
