This is one of the best airbnbs that I have stayed and the location is perfect! Close to Karakoy station. Galata tower is also very close to the place. There is a lovely cafe downstairs. The airbnb is very clean and has got all the things that we needed during our stay. The owners reply to messages very quickly even late hours of the night. They allowed us to check in early and checkout. They allowed us to leave our baggages after we check out.
If we come back to Istanbul, we will definitely choose this place again. Thanks for the lovely stay!!
