Excellent place to stay in Istanbul. Very central location, most touristy things are 10-20 min walk from here. Host is very good with communication and logistics. Anna welcomed us even though we arrived pretty late at night, and was there to see us check out as well.
The place has adequate amenities, and is quite cosy ( does get a bit too warm with the heating on in winter, but you can switch the radiators off yourself if needed). Good cafes and restaurants nearby ( I'd recommend nasip et kebap right around the corner, incredible food and amazing prices)
