Isik's flat is very comfortable and beautiful. We stayed there for 4 days with 2 children (9 and 1 years old) and we could not expect better. Isik had already prepared a crib for our baby even if we didn't ask for, the flat was very warm when we arrived and there was also a huge bottle of drinking water (for those who don't know in Istanbul you cannot drink tap water). Isik explained us in detail how to use everything (even washing machine) and left us an Istanbul Card, very useful for public transport. The flat is very well equipped and also very nice. It is silent even if 5' from the chaos of the Takism square. From Taksim it is easy to get everywhere in the city. I would for sure come back here.
