We really enjoyed staying at Sebnem's place. Everything is exactly as advertised on Airbnb. We spent the month of October in Istanbul and the apartment was perfect. It is super quiet with everything you need in the apartment. Located in Sisli, you have every kind of food store, bakery, kebab shop, etc, etc within 5 minutes walk. You're 10 mins walk from Osmanbay metro stop, which takes you to Galata or Old Istanbul in 10 mins max. Sisli is very local and we didn't encounter any other tourists for the month we were there. We highly recommend staying at Sebnem's place.
