As someone born and raised in Istanbul, I can say that this place's location and view are difficult to match. It's very much within walking distance to most attractions in the Beyoglu district, be it Cihangir, Galata, or Karakoy. But it's also just far enough from all those places so that you can have a quiet and peaceful evening. The view stretches from the Dolmabahce Palace all the way to Blue Mosque. All things considered, it's a unique place.
One thing to note, there was an ongoing construction in the neighboring building, which was beyond their control, I suppose. It didn't bother us much during our stay as we were mostly outside the place. But if you'd like to spend some time in the home during the day, you'd better check on this with the owners.
