Hello! My apartment is located right outside of Topkapı Palace's walls. Walking to places like Hagia Sophia, Blue Mosque, museums etc. will take 2-3 minutes on foot.
The apartment has Wi-Fi, hot water and heater. It's private, only you will have access to the apartment during your stay.
You can reach anywhere in Istanbul with public transportation easily from the apartment; tram station and Marmaray Metro is 3 minutes on foot, busses are also in very close proximity.
