I had a really good time in Istanbul with Fatma and Hasan. They have been so nice, helpfully and friendly. I really felt home there. And the room was cosy and nice too. And I really enjoide the roof terrace in the house.
Also Tarlabasi in Istanbul is good place to stay, only 7 minutes to Taksim and 5 minutes to Istiklal.
I can totally recommend that place at all.
