Yilmaz is great host. He attended to our needs and requests promptly. He was really nice and helping, kept asking if we need anything during our stay to make it better.
Our flight was early morning and early check in was not an option as apartment was occupied but still he did his best to check in us 90 minutes before regular check in of 2:00 PM.
He left couple of sweets during our stay and a departing gift, which was so thoughtful of him.
Our airport transfer for return to airport was late and Yilmaz helped us in communication with the local driver and we made to airport in time. (Our flight was delayed by Turkish Airlines though).
It is very affordable and good value for money. Location is best. There are lot of recommendations he gave us for attractions, shopping and eating out.
Overall amazing experience and we were able to explore old city Istanbul very easily.
