I'll start with the positive aspects:
1) The location is perfect - there are many different cafes, restaurants, shops, etc. nearby. Taksim is 200-300 meters away and there are always a lot of people.
2) Check-in was perfect - I only needed to know the code from the box and the keys were already there.
Negative sides:
1) Noisy neighbors - for several days in a row, neighbors made noises and had rows at night, did not let us sleep at all.
2) Cockroaches - we had to kill them manually, as they disturbed us.
3) The TV does not work - we wanted to watch football, we literally could not turn it on.
4) Windows - you could hear almost everything that happened in the street. Sometimes it was very difficult to fall asleep because something was happening outside.
5) The washbasin did not work properly - water washed away very badly. I had to help with my hand, otherwise, the water would remain in the washbasin.
6) The refrigerator did not stand tightly - it swayed constantly. When you open it, it bends to one side.
7) Some of the towels were stained. We simply didn't use them.
8) There is no corkscrew - we wanted to open the wine, we did not find a tool for this. I had to use a fork.
Overall, I would not recommend this apartment.
