DAY 4 of my "Best in travel 2017" : Istanbul, Turkey. I had wanted to travel to Istanbul for years and when I finally made it there, I immediately fell in love with this incredible city. There are countless reasons to love Istanbul - the history, the architecture, the food, the people - but for me, of course, the number one reason to love it is the cats. There are cats everywhere around the city, and they are very well taken care of by pretty much everyone. Here is Gli, resident cat at the stunning Hagia Sophia.
