Our second stay at this flat - first time was ~ 2 weeks, now only 2 days before our flight home. Yakup is VERY attentive and helpful. Flat is huge and has all the amenities you need maybe except for a wine bottle corkscrew ;-)
Bed and bathrooms are comfortable, kitchen well stocked, super location just off of Taksim Square.
Wifi is sometimes spotty so if on a work-vacation, consider having a sim card.
Thanks Yakup for your help and seamless check-in!
