Burak was out of town during mye stay, I met his father at the near by business center, and he took care of check-in. ANd took me to the roof and showed me the view to Bosphorus, and gave me my first chai (turkish tea).
Buraks father offered complimentary bottles of drinking water for the whole stay, which was very appreciated. I don't know if they always do that, but it was a very nice touch!
Burak had great communication via messaging, and checked that everyting was OK. I had no special issues while I stayed there, but i trusted that Burak would try to help if I had needed that.
The appartment was a little cold at night when I stayed there (late november). But it is probably very pleasant in the warmer months.
Over all a good stay, and very good hosts.
