Positive aspects: Kenan’s apartment was very clean and tidy and perfectly located for easy walking access to all the recommended tourist sites in the old town. It is comfortable and very good value for money. Kenan is a very good host; he was there to meet me on arrival and was available for help when I needed it.
Negative aspects. Unfortunately there was building work going on in the apartment above when I stayed so it was a bit noisy during the short periods I spent in the apartment during the day. It was much better in the evening. There is also only aircon in the living room but not in the bedroom. I found it difficult to find the right balance to keep the bedroom comfortably cool at night.
Kenon can arrange for you to be met at the airport and dropped at the apartment in a smart air-conditioned Mercedes. Cost 750 lira (40 Euro). Cost for a standard yellow cab is 400 lira.
In Jun 22 many of the main tourist attractions in Istanbul were either closed or partially closed for renovation. This includes the Blue Mosque; you can see a bit of the newly renovated ceiling but none of the walls. If you can, delay visiting until next year.
