Area: the area of the apartment is great, its normal neighborhood approx. 10min walking to istiklal, and 5min walking to the new galataport area, with great view onto the sea and nice cafes and restaurants. The apartment had a view onto the Galata tower, which was also just a couple of minutes away. As mentioned in other reviews, a grocery shop is in the same building as the apartment, supermarkets, bakery, restaurant and coffee shops are also available within minutes.
Apartment: The apartment was located in the top floor of the building, elevator for easy access was available. The place was super clean - we were two adults, and had more than enough space. The big sofa in the living room is able to be transformed into a bed, which was very comfortable. the kitchen is fully equipped which was great as we were able to use to big balcony for breakfasts outside before starting the day. smart tv and internet were functioning perfectly. Bathroom was equipped with towels, small care packs with necessary utensils like shower gel, etc. overall the apartment is very nice and quiet, we could not hear any noise from the streets.
Check-In/Check Out: It was super easy to communicate with Can via the messenger function, his response time is very fast. As I wasn't aware what time exactly I would arrive into Istanbul, Can arranged for the keys to be available in a secure key box so we were able to check in independently. Check Out is equally simple. As the apartment is centrally located it can be a bit difficult to find a parking spot if you arrive with your own car, but Can was able to recommend a parking spot at a discounted rate so our car was parked safely during the stay, that helped us a lot.
Overall: great place, good value, amazing location, highly recommended.
