Nice cosy spacious flat with everything that needed. Polite and quickly responding host. I had unexpected change of dates and she found diplomatic compromise. Her neighbour is always ready to help tenants and is often nearby. And the whole building was recently renovated and looks modern, it is quite uncommon for Üsküdar. Süpermarket is not so far away. In kitchen there is everything needed for cooking, including all small equipment.
I don't have any issues with not spacious bathrooms ( someone mentioned it in comments, so I'm adding that it's quite common thing in Turkey), rest of flat is spacious, so I was absolutely comfortable
