I stayed there for a week, it was one of the best places I stayed at in Istanbul. The host Memet was very communicable, he responds to messages quickly and get you everything that you need. He was very nice and took me for a short tour around the block, there's a lot to do from bars to restaurants to everything.
The place itself exceeded my expectations to be honest. Very spacious with lots of sun light coming-in in the morning hours. You can also enjoy a really nice garden as I did. There is everything you need inside the apartment but you need to get your food and water. For food I highly recommend a restaurant 1 minute walking from the apartment down the street, its called Tacos'ist its a family owned business and has really good food.
Generally speaking, I would certainly stay there any chance I get.
THANK YOU Memet for everything!
