Mehmet's brother Ali checked us into the flat and was so helpful throughout our stay! He took time to show me key things on the map, gave restaurant recommendations (which were fab!) and arranged an airport transfer for us. Great location in a historic building (some renovations going on nearby, but we didn't hear anything!), very close to Sultanahmet District (Blue Mosque, Hagia Sofia, Topkapi palace). Highly recommended- would stay again.
