Beautiful location, fantastic apartment and experience.
Ömer was very accommodating and answered any and all questions we had. With a private doorman that is there to help guide us as well, we had no problems getting acclimated.
The location is so close to the Galata tower that you can reach there within 30 seconds of walking. It also makes it supremely easy to navigate yourself back if you get lost and your phone is dead as you can just look up, find the tower and walk towards that.
As a tip, go and have some fresh juice in the shops nearby. They are amazingly delicious and cheap too! :)
