Highly recommend Mubarek’s place! Extremely walkable to everything in the old city (Hagia Sophia, Blue Mosque, Togkapi Palace, Grand Bazaar, Spice Bazaar, etc.) - my wife and I didn’t even need to hop onto the Metro until a few days in since there was so much to do near us! The place is also conveniently next to the Metro when needed. Finally, Mubarak and staff were extremely hospitable and friendly - they offered us Turkish coffees and teas many times, including noticing when my wife and I came home soaking wet from the rain and they knocked on our door with tea to help warm us up! Would come back again!
