Nice and cozy flat with an astonishing view on Bosphorus and Bosphorus bridge. If you do not fear to go on your feet to 6th floor and can shrug off some night street city noise (as we did) then it would be really great choice. We stayed at Ozan's flat for a three nights. And we definitely loved it - really great location (5-10 minutes walking from Taksim sq. and Istiklal str.), a lot of nice caffes and small restaurants around, polite and reliable host, reasonable price, clean and bright flat with great view - these are main advantages among many other. Of course, lack of escalator and washing machine might be a disadvantage for someone, but I believe it is really great choice for a pair of backpackers to stay for a couple of days. I can definitely recommend it.
