Great Host, always willing to help. The location of the apartment was very convenient for us, walking distance to the Blue Mosque, Topkapi, Ayasofia...
The air conditioned rooms helped a lot as it was hot throughout our stay.
Tips for Istanbul visitors:
Be very careful if thinking of transiting by Taxi, if the drivers sense that you don't know the city, you would likely be robbed no matter how careful you are. (There is some good apps for Tramway and Subway)
