We spend some great days at Cansu's place. The apartment is very cozy and had the perfect size for us three friends. The beautiful rooftop has a great view over Istanbul and was a nice place to hang out. The apartment was very bright and equipped with everything we needed.
The location is also great, it's in a calm street but right next to Moda, where you find everything you need, with lots of cute cafes and bars. I can recommend Cansu's place and hope to come back one day.
