The apartment is in a fantastic location with regards to how close it is to major tourist attractions in Istanbul, along with bars and restaurants. Sedef was incredibly responsive with communication and very flexible with many different things. Sedef also warned us about the fact that it can be noisy at night as a result of one of the bars or clubs close by. Do be wary that the music and bass is very loud and you'll need some top quality noise cancellation devices to curtail it.
The apartment has a great bed and all of the amenities one needs when travelling. It's really clean and modernly furnished.
