Oyku was always helpful, but the combination for the key safe is very hard to read in the angle of the light and at the end of a flight from Australia and dragging suitcase up 3 flights of stairs that were not mentioned (i have arthritis in knee) it was very frustrating. Had to go through it all again in coordinating the repairman sent when I reported broken sofa leg and leaky tap - I was asked to leave key in safe again and again had trouble with it on return. Another thing that should be mentioned in advance is that no toilet paper is allowed to be flushed in toilet because it is a very old building - it has to be gathered in bin and disposed of by the guest in a public bin all rather unpleasant. However the flat itself is neat, roomy and pleasant , nicely furnished and it is in a good central location from which to explore Istanbul. Oyku is a friendly host too.
