Mehmet is a very cool guest ! His flat is very nice too. From the terrasse, that is amazing, you have a pleasant view on Istanbul hills which i didn't expected from the pictures. The flat is very well located in Besiktas from where you can easily go everywhere (calmer neighborhoods in the north, centre, asia) thanks to the various buses and ferries nearby. And many cools places to hang out around, including good coffee and bars. Recommend !
