I stayed here for three weeks in October 2020. The apartment is in a great location, very clean, with a good kitchen, good shower, and comfortable bed. The elevator helps a lot. It's a very light place with a nice sea view from one corner. Missy was friendly, responded to messages when needed and left me to have a good time.
The only problem was the wifi, which is weak and not up to today's standards. Like many people these days I have to be on Zoom meetings a lot and the wifi wasn't strong or stable enough. It's possible and not too expensive to have very good wifi in Istanbul now so this should be dealt with.
