Kalen is an amazing host and his house in Fatih is perfect for your stay in Istanbul. The house has everything you need and the view from the balcony is a great bonus. The neighbourhood is really nice, especially after seeing it with Kalen's indispensable guidance. It is located close to the historical sites and at the same time 5 min from an important metro station. Kalen is without a doubt the best host I've ever met, and I really appreciate the time and energy he puts into his work.
