I've stayed with Airbnb in 15+ countries, and Serdar is probably the best host I have met!
He accommodated our special needs for check in, check out & luggage storage, as well as always checking with us everyday if everything is okay. The place is also very stylish, has amazing view of the Bosphorus bridge, and also very big.
The beds are HUGE. Nice bathrobes. Safe location. Very attentive host. 100% recommended!
