I really enjoyed staying at Hakan's place. The flat is equipped with everything that one need to live comfortably. The place is also good, there are grocery store, pharmacy a lot restaurants and kafes around it. Transportation knot is also very close, 5 mins walking to metrobus, bus station and taxi park.
Hakan is a great host. Met me and took to the apartment and showed around. Was quick to repsonse any questions I had.
Highly recommend for anyone visiting Istanbul for business trip or solo travelling
