Hikmet's place is right in the centre of Istanbul's old town. He was an extremely helpful and thoughtful host - very good hospitality, we couldn't have asked for more. We were able to leave our luggage in his tour company shop front (that is right next door) to the BnB on check-out day which was really nice of Hikmet to offer - gave us some extra time to see Istanbul before we headed to the airport. Great place! Only thing to note is that the place is situated downstairs rather than above ground - which was fine for us!
