I had a wonderful time at Hazar's place. The location is absolutely amazing, close to all of the action in Kadikoy, surrounded by cute cafes and within very short walking distance from bars, restaurants, the water and public transport links to the rest of the city. The apartment is cozy and comfortable, and feels very much like a real home. The kitchen facilities are pretty basic, but with this many great and affordable food options on your doorstep, you won't want to cook anyway. Hazar is really helpful and friendly. I stayed for two-and-a-half weeks and he'd contact me every few days to make sure everything was OK and that I was happy. Great host and apartment. Would definitely recommend, and would add that this is probably the best neighbourhood to stay in Istanbul.
