Let me start it this way.....
Guner is one of the most genuinely kind and honest host that I have ever come across. He puts the satisfaction and comfort of his guests above all.
He offered us a beautiful, convenient, clean and centrally located studio at a very very good price. We (me and my wife) were highly satisfied with our stay at his place.
Some of the features of his place:
-utmost cleanliness
-very convenient location
-shops, restaurants and market nearby
-the kitchen has all possible utensils that one may need.
-stocked refrigerator for the first day of visit
-guner or his colleagues were ever present to cater to our requests at all times
-the apartment is exactly like it is in the pictures.
-guner always helped us with the booking of cabs
To top it all guner took great care of us when we missed our flight and came back from the airport, he offered us a very beautiful room In his brothers building just next to this one at a very very decent price. Trust me any other person would have tried to take advantage of our situation and would have extracted money from us. He will give you best and honest deal.
In my opinion you will not find a better host in all of Istanbul.....if you don't stay at his place you will surely miss out on a lot.
We are definitely coming back to our new friend in Istanbul.
