I really enjoyed my stay at Mersin's apartment during more than 2 months of my exchange semester at Koç University. The flat looks exactly like in the pictures and is very cozy. I have hardly seen the neighbours but even if you invite some friends in the evening, have some drinks and play music they never complain. The location is perfect - no noises from clubs/traffic/restaurants and at the same right in the heart of the city, 2 mins walk from the main street Istiklal, 10 mins walk to the metro (but you can also take 2 bus stops and you reach Sishane). There are many markets nearby and every Sunday there is a local grocery market on the street. Mersin was a perfect host, he always resolved all the issues regarding the flat as soon as possible and was very kind. Though he lives in Stockholm his assistant is always there to help you. I highly recommend this location both for short- and longterm stay. Thank you so much! You really contributed to my amazing experience of living in Istanbul.
