Isik and his apartment were great! The apartment is centrally located, a stone's throw from Taksim Square, and was the perfect launch point to explore the city. Isik orchestrated our pickup from the airport and met us at the apartment promptly. He's super chill, friendly, helpful and well organized, and the apartment itself is great. There's even a little patio. My one note is that the hot water is a little less than hot, but otherwise, I'd definitely recommend Isik and his beautiful apartment. And check out that ceiling. 100 years old, he said. Totally beautiful and totally added to the vibe.
