Berkan is really friendly, he is always there if you have any problem and he will make you feel welcome since the first minute! The spot is close to taksim, istiklal and all the areas surrounding, right in the middle of everything. The house itself has its historic charm and it's quite beautiful, little bit old but clean and fairly well equipped. One thing you might consider: the area is pretty alive (there are some pubs close to the building) and gets noisy at nights, but with earplugs it's easily fixed.
