Akin's place is at the heart of Fatih which means it's close to lots of touristic places. Grand bazar is literally 5 minutes walk away, blue mosque, topkapi sarayi, and Basilica Cistern are just one metro station away. Other than that, there are many eateries and restaurants around the corner, some of which are open till very late.
The apartment looked exactly like the photos and everything was in good shape. Akin is a friendly guy who kindly suggested lots of help with everything he could.
We had an incredible two weeks stay there and we'll call Akin again if we come back to Istanbul!
