This one I tooked behind Hagia Sofia. There is a small niciest small street behind Aya Sofia, and in the evening it's even more beutiful. And it's so quit their... you wouldn't even say you are in Istanbul!
Just find the time to go there in the evening. You will not regret it!
Sunsets are always beautifull and everwhere in the world. They leave you some unforgettable souvenirs and you miss them later on.
Here in Istanbul you have one of them...Go to Usküdar , go to Moda and find one of the several teagardens (any Çay Bahçesi ) and sit and relax and enjoy the panaroma..
One warning our teagardens dont serve alcohols .If you want to also enjoy that then you should go to a restaurant or similar at same area.. Teagardens are mostly outdoor places but most has also an indoor place like my favorite one in Moda
you can there also play cards or backgammon and beat your friends but no gambling is allowed...
Too much has been already said about sunsets in general and sunsets of Istanbul in particular, no need to describe them....
However the feelings arising when seeing them are needed to be shared....
