Hatip is really a great host. He helped us with any possible request from us, was always available via chat and call.
We used airport transfer arranged by him several times and it was great. Suggest others to do the same instead of arranging yourselves because the house is located on one way street and maybe not easy for all taxi drivers to find the location by using GPS.
The house is located near Sultan Ahmet square which was a plus. These days it is almost impossible to use taxi without getting stuck in traffic in Istanbul even during weekends, therefore better to book a place near centrum.
I recommend this place to others.
Thanks a lot Hatip for the hospitality and great support during our stay.
