I really enjoyed staying at Hazem's apartment. I would definitely recommend renting it!
it is very clean and cozy and feels like home. This apartment has everything you need! Most important for us was its location..in family oriented neighborhood, just few steps away supermarket, restorants, cafes, nice shopping area, Turkish sweets shops.
If you coming for surgery or any medical reasons the Memorial Hospital located only 8 minutes walk away from the apartment.
if we come back visit Istanbul we would stay at Hazem's place again for sure!
