Barbaros was very communicative and accomodating! The flat is at the bottom of a hill, so keep that in mind if you don't want to exercise every time you want to go up to the more touristy areas (like Ayasofya). Lovely restaurants at local prices nearby, and the neighbourhood has a "family" vibe. My only issue with the flat was that the WiFi was spotty — but with how inexpensive data tariffs are in Turkey, I was able to make do. Lots of good hot water if that's important to you!
