The apartment was great!
I really enjoyed staying there, everything was spot on! The place is small but everything in it is arranged really smart. Especially I like how sleeping bed is placed next to great windows so you can enjoy view preparing to sleep and great sky and landscape welcomes you in the morning. And the view is amazing! You can see the whole town there. The only thing that was off is distance from main attractions in Istanbul (city center) so you need to drive a bit to every place that you want to visit. But I was aware of that from the beginning so it was no trouble at all. Luckily, taxi is not expensive at all.
All in all, it was a pleasure and I recommend it fully.
