The unit is clean and tidy, as per the pictures. We were greeted by Yavuz's brother (we caught his name but are not sure how to spell it). Our unit was on the second floor. Our host helped my husband carry our luggage up and down the narrow spirally staircase with no problem at all. He was very helpful and responded to our queries promptly. He also provided tips on getting around Istanbul, which we appreciated very much.
We had him arrange our transport transfer, which made our trip from/to airport a breeze.
