Highly recommend this place. Very beautiful place. It's simple, still you will find everything you need, moreover 2 terraces and lots of windows are making this place unique.
You will wake up with an amazing view on Istanbul (including Galata tower). The only thing that you need to remember - the apartment is under the roof and you have to walk up to the last floor (no elevator and narrow stairway), still views are definitely worth this.
Moreover, very tasty Turkish breakfast is included (in nice place nearby).
Faruk is very hospitable and help a lot. No problems with check in / check out, flexible approach, nice communication.
