That was an unique experience included a good apartment and very kind and hospitality person such an Ülfet. I'm very glad this apartment was a part of our airbnb journey.
You will have everything in common to use. Equipped kitchen, bathroom and etc. The room seems cozy and this is a place where you want to go back after a day of exploring Istanbul. There is gonna be a street full of cafe/restaurants and small shops next to the apartment so no problem to get some local food and etc. Also there are some malls in 10-15 mins by walk you will see them on the way to metro (you definitely should check Canyon mall, love this place).
