The truth about Basel is that he becomes your friend than your host! He is easygoing and flexible to his guests and provides you with useful local tips. He is easy to reach out and always responsive.
The apartment is super clean and comfy. You would have whatever you might need here. My parents and I were Basel's guests and we all felt like right at home.
The only fact that you have to encounter is the distance to Istanbul's sightseeing and touristic area which might take you 30-40 mins by car. The rest is super fine with the flat's location.
Definitely recommended!
