The best host I've met. He waited for us even we arrived on 2 a.m. for check-in. He can help you with all the info you need to visit Istanbul. We receive an amazing Turkish breakfast on the "terasse" during one morning - "on the house".
The apartment was clean and exactly like in the photos and description. He helped us with our luggage after check-out because of our late plane, so we got a lot more time to visit the city.
I'll recommend Hikment apartment to our friends and we definitely will come back to him on our next trip on Istanbul.
