Yusuf's place is as described and completely met our expectations. Though we did not get to meet Yusuf, Erol was very helpful through our stay along with two of the front desk staff. They arranged pick-up from airport and also called a cab to have us dropped back. Erol provides a detailed itinerary and customises it according to our liking. We had a friendly banter about Uber tricks in Istanbul which was very insightful. They also helped me have food delivered which was a big plus. All historical places are 5-10 minutes walking distance and we could not have chosen a better place rest our tired legs. Thanks again Erol and team!
