Hasan's place is sparkingly clean and an amazing location! Walking distance to all the hustle and bustle of Taksim Square but still far enough for it to be quiet. Very cute, trendy, hip neighborhood of Cihangir/Karakoy/Topkhane. Hasan lent me his Istanbul Kart to take the metro and even woke up at 4am to help bring my bag down the stairs and sent me off to the airport! Great host, will definitely stay here when I visit Istanbul again!
