Our stay at Mustafas place was really enjoyable. We got a clean and spacious room. The kitchen was well equipped and we could wash our dirty clothes. Mustafa himself was a really great host. He is calm and warm-hearted guy who helped us with any questions or problem we had. Twice he invited us for breakfast and this was really something special. It was delicious and also an authentic impression of Turkish cousin. Kadiköy (the neighborhood) was the most relaxed area we discovered in whole Istanbul. For us it was 5 out of 5.
