Alkan is the sweetest host you will meet in Istanbul! The communication was always very simple and fast and on top of that he even offered to show us the area and always made sure that we were comfortable everywhere we were going.
The flat is really nice, it has everything you need and it's super close to the Taksim Square, so you can go everywhere by foot.
All in all we can really recommend this flat and with Alkan as your host you will be more than happy :)
