The apartment was excellent. The location is 150 meters down hill from Taksim Square— but it was very quite inside, even with the windows open. Apartment is well furnished & clean. Beds were comfortable. Every restaurant, cafe, grocery or public transit was only minutes from the front door.
Only things to note:
It was quite difficult to use the toilet, as the sink is so close, so we had to sit sideways. Additionally the wifi wasn’t fast or reliable. So if you’re planning to work, you’ll need to tether to 4g device.
