Awesome place with a great view through panoramic windows! Also there is a public terrace just 2 floors up with an even better view.
We've enjoyed our short stay as the flat had everything we needed and the location was just a couple of minutes walking from Istiklal.
Also Lisya was extremely friendly and helpful, we've forgotten a coat in the flat and she helped us to get it back when we returned to Istanbul after a couple of days.
