Caglayan is very nice, friendly and hospitable host!
Location of the apartment is good, very close to public transport hubs. Supermarket is just 20 steps away from the apartment. Plenty of small cafes, a very popular area full of artsy places and overall a peaceful neighbourhood. Flat was clean, tidy, common room had a very stylish furniture. The place was warm in the winter time and had all basic things you need. Bed was good and comfortable. I would totally recommend staying at Caglayan's apartment and would stay at her place again the next time I am in Istanbul.
