We were only 4 days in Istanbul, but we liked everything. The apartment was clean and everything is as in photographs. There was only one bad moment, we arrived, the day before discussed what time we would be, we were a little late because the plane was late. But in the end we waited 3 hours, because the host was asleep and it was impossible to wake up him. In general, the apartment is clean, the plumbing is also all clean. The area is really not very quiet and you have to sleep with the windows open because there is no air conditioning, but this is the center of Istanbul! And the price is quite low, which made us happy. The apartment had a cooking stove and a washing machine. We rarely saw the owner at home, so everything was quiet in the apartment. I recommend Mahmut as a host if you come to travel.
