Great location, right off of Istiklal street, making all the sites of Istanbul very accessible. It's tucked away on a side street, so there it's very quiet at night.
Additionally, it's right by Leb-i-derya which is a stunning rooftop bar, and Yeni Lokanta which is a new Turkish cuisine restaurant with a fresh take on traditional Turkish cuisine.
The apartment is built adjacent to a school, so if you're home during the day, it'll be quite noisy in the apartment with the children playing in the yard which is literally outside the window. If you're out sightseeing, this isn't an issue, and obviously on the weekends, it was completely quiet. Just a note for travelers working remotely, like myself, though a pair of headphones easily mitigated the noise factor.
Kursad was a very gracious host, who was very quick to respond to comments and resolve any issues I had.
One note for non-smokers, this apartment is adjacent to another unit which is also managed by Kursad, so if those guests are smoking in their room (which is against the policy), the smell is very strong in this unit as well. When I complained to Kursad about this, he kindly moved the other guests to another unit, which was really nice.
For the price, this unit is an amazing deal. It has everything to be comfortable and self-sufficient. I have some dietary restrictions which makes it easier for me if I just cook my own food than trying to communicate with restaurants, so the kitchen set up was simple but sufficient. The furnishing is minimal, stylish, and very comfortable. Everything is new and super clean. Would highly recommend!
