Our stay was really clean and near to Blue Mosque & Hagia Sophia. Its a walking distance but with steep slopes.. so make sure u wear proper shoes. Going to the airbnb is quite far from the airport. There is no lifts so you'll have to climb the stairs. The guy (sorry i forgot your name) was there to help us with check-in despite us reaching at wee hours. They have a booklet on recommended food and places to go too. It was really helpful. Overall its a great and recommended stay. But not for elderly as its steep to climb the stairs.
