Izel, Doret's brother, is a wonderful host. He was very thorough in his introduction of the amenities around the apartment and how to move around. As a result, we've tried the local ferry to Kadikoy, and also taken the tram to Blue Mosque and the Tunel back to the apartment without a hitch.
The location of the apartment is excellent. Lots of shops and eateries around Galata Towers which is a great landmark if you return by cab.
We have great three day break in Istanbul. Thanks again, Izel.
