Omer's renovated historical apartment is located in a great and easy-to-reach spot just by the Sishane Metro station and the Tunel Funicular exit. The apartment is well-equipped with new appliances, and the WiFi, Smart TV and AC worked fantastically.
The automatic check-in/check-out system was also very convenient for us as we had to leave for the airport quite early in the morning. We absolutely recommend Omer's place for anyone visiting Istanbul.
