This place is amazing and clean, I liked it so much, sadly, when I traveled we had a bad weather and my flight delay so much, so I didn't had enough time to enjoy the apartment and the city. But if I travel to Istanbul or have a long layover there again, definitely I would stay here!
And Bilo is a nice person. He picked me up at the airport, and wait for me even when my flight was delayed and drop me off to the airport again. Before I meet him I usually stayed in a hotel near the airport, but now this place is my favorite.
