The apartment is in a perfect location, close to Galata Tower, Istiklal street & Taksim square, and you can walk to the other side of the bridge where you could reach Fatih & Eminönü.
Omer is nice and helpful, he waited for us at the mentioned check in time, helped us with the luggage, check in was very easy and simple, the apartment was super clean and equipped with everything you would need.
All in all a very nice experience.
