The apartment was exactly as it's shown on pictures. Spacious, very bright, clean and has a nice balcony where you can relax cause it's very calm and quiet. The location of the apartment is great. Tram is less than 5 minutes away and you can get to Istiklal, Galata, Taksim or Sishane metro station in 15-20 min by foot. Just keep in mind you have to walk up but that's typical for Istanbul :). Sultanahmet is also close and usually walked all the way there cause there is so much to see when you're exploring the city by foot.
The apartment has all you need for comfort staying. There are more kitchen amenities than you might need, big TV (altough you probably won't need it), washing mashine, dishwasher...
If you are looking for an aparment that is nicely decorated, close to everything and yet quiet, this is a perfect choice.
The communication with both Didem and Özgür was easy and they were at our disposal for everything we needed and more :). I can give highest recommendations for this apartment.
