Great flat in the heart of Kadikoy - you'll definitely feel the vibe, because you dive into it right away you leave the building!
Flat has a huge couch, where all you folks can be accommodated for a night talk, two (!) bathrooms, what is extremely helpful for big companies, decent wi-fi and even dryer for clothes!
Communication with Yavuz is perfect - you will not feel lost with him and it's very convenient to check in/out.
Definitely worth renting when you're coming with your group of friends, you will not be dissapointed!
