This location is perfect and host is friendly and respond quickly. Highly recommended this place. My friend and I plan to rent this Airbnb again if we visit Istanbul.
Pros:
1. Location. 10 minute walk to Dolmabahce Palace. 5 minute walk to Metro station.
2. Host. Emirhan and his team are very helpful. Emirhan recommended me a travel agent to arrange the airport pickup for my 7 people group. Ms. Tuna helped us to have early check-in and we were able to seamless completed pick up and check-in.

Cons:
1. Stairs. Other review has also mentioned stairs as entrances, without elevator. For senior people, it might be challenge to lift the luggage and walk the stairs.
2. Curtain. Each room's curtain is thin and can hardly cover the window fully. For people sensitive to light during their sleep, the curtain might be a downside.
Overall very positive experience and reasonable price. We really enjoyed the view of the house and the hospitality of Emirhan.
