Fatma's place is located 5 minutes away from Istiklal, a beautiful boulevard with lots of shops and coffee places. It takes you about an hour to walk to all the tourist attractions like the Blue Mosque, the Grand Bazaar and the Dolmabahçe Palace to name a few. She and her husband Hasan are very welcoming. They waited until I arrived at 2 am so that they could let me in. Totally recommend!
