I stayed at Cihan's place for a month. I have never experienced Istanbul this way: you are very close to public transportation options as the bus stop is right in front of the door and brings you to the ferry or Marmaray. As the apartment is next to Kuzguncuk Pier, you are able to order a sea taxi too for a more comfortable ride to the European side.
The traditional details in the room, the private hammam were amazing. Cihan is also a great host as he has many tips about where to go or where to eat. He is a doctor and working from home.
