We stayed at this flat for a week over New Year. Koray, Pelin's partner was in good contact before we arrived, with excellent directions and he was there to meet us at the flat which is indeed very cute, warm and in a fantastic central location surrounded by lots of hipster coffee shops, food shops, restaurants and vintage clothes shops, it's buzzing and all the locals we met were very friendly and chatty indeed!
It's very well located and served by the metro and trams or just by walking, easy for all the sites including the Mosques,Grand Bizzarre, Museums,Instanbul Modern and the boats to get across to the Asian side,and at night you don't really need to go too far to have some fun.
We loved the flat, perfect for a couple for a few days stay and despite the area it is in the living room/bedroom is at the back so it is very quiet indeed.
They were the perfect hosts, available for any questions we might have and even doing our washing for us. We would definitely recommend this studio to any of my friends and would love to return one day when it is summer. Thanks for everything, we had an incredible time!!
