Probably, as many guests before me, I used Samet's accommodation for my overnight layover at Sabiha Gökçen airport. I came from Muscat and had a connecting flight back home to Munich the next day.
It's cheap and comfortable. You don't have to sleep at the airport's waiting area or pay more than 100€ to one of the nearby airport hotels.
Unfortunately, I didn't met Samet in person. But I send my request for staying at his flat/room really spontaneously to him and he made it possible for me to stay at his place and replied to my messages really quickly.
Thanks for that, Samet :-)
