We stayed in Pelin's house for 3 days and think Pelin' flat is best in Istanbul!! We could enjoy everything of Taksim(the most popular and new region in Istanbul). The house was also very clean and well equipped for all aspects. Especially the living room with wide screen was perfect for taking a rest.
And the best thing of the staying was the host Pelin and her partner Koray. They are so quick for our any requests, even though it was late night. And also very kind for treating us all the time.
I really want to recommend this flat for you if you're going to visit Istanbul! It's absolutely wonderful house:)
