The location is perfect - just a few minutes from the Taksim square, with a lot of food places and shops nearby. The housekeeper is very friendly, allowed us to check-in earlier than we were supposed to, and check-out later as well.
The apartment was clean, and had everything one might need like towels, soap, dishes, bedsheets, hairdryer, etc. The only thing we had to bring with ourselves was personal hygiene items like shampoo and toothpaste.
I definitely recommend this host and this apartment.
