We had a comfortable three nights in the apartment, which is a nice base for a trip to Istanbul. All check-in and contact with Yildaray was virtual and worked perfectly. Yildiray was very responsive to any queries that we had. We had no issue with the apartment. The only possible issue is that the apartment is on a road with a steep hill that you will probably have to climb. That is fine if you are reasonably fit but might not suit if you are old or infirm. We loved Istanbul - it is one of the world's great cities and, with the devaluation of the Turkish Lira, it proved to be a relatively cheap place to visit.
