My friend and I rented Ulas's apartment in Beyazit / Fatih area for 4 days.
He was a very hospitable, wonderful man, generous and very helpful.
The apartment is very good, modern design, clean and like hotel finishes.
Ulas and Gorkemm didn't let us down at all, they catered to all our needs and was very kind, they provide us desserts as a complement as upon our arrival to the apartment, and also gave us quick and great laundry and ironing service, even allow us resting in one of the vacant flats till we go to the airport, and that's really worth mentioning for the guy's accountability.
Of course, there are some general negatives about the "Fateh" area (This is of-course Not because of Ulas), such as its overcrowding, and the location of the building on the side of a hill, which makes reaching it a bit tiring on foot, and the stairs in the building are difficult to climb, and the difficulty of finding a taxi in the area.
I must say it: "what makes our stay easy is Ulas' friendliness"
