Have stayed in around a dozen Airbnb locations in Istanbul and this rates as one of the highest as it's in a perfect location a short walk from the Havaist airport bus to Taksim, near to a cut thru to Istiklal Street for shopping and best of all close to all the best restaurants around Cihangir.
Check-in was keypad so no hanging around and the street is one of the quietest I ever stayed in. No traffic at all, no mosques nearby and quiet neighbours. There are two local schools so great to hear local children at play from about 8am on weekdays.
Great breakfast spots are nearby and loved the local cats and street dogs especially an ultra friendly 3 legged dog down the road!
Fully intend to return here next May on my next trip. Recommended!
