Erol’s place is a fantastic option. It’s located right around the corner from Istiklal Street and Taksim. Erol was the best airbnb host I’ve dealt with. I had to switch airbnb’s last minute and he helped me with self check-in at around 2 am. Even then, the process was very easy. It was a clean place, great location, and the wifi is really good if you need to work. Definitely recommend!
