Billy (or Bilgen hanım, that was how I called her) was really kind and her flat is, as it is described, cozy and in a good position. You can easily reach every destination in Istanbul, if you want.
You will have a lot of opportunities to buy groceries near to the flat. You will have a lot of parking spaces. That’s important in Istanbul.
I can warmly recommend her flat. She is a good host and well organized 👌🏻
