This is honest review for future guests:
First day when we arrived we did not have heating and hot water, so we could not take a shower until tomorrow. Tomorrow host explained how to fix the pressure on heating machine, after that heating started to work and we had hot water. Once you first enter the apartment you can smell bad moisture, so we advise to buy something to fresh up the apartment like we did, otherwise bad smell will be there.
In the apartment you will get 2 towels and 2 toilet papers, if you want extra pair of sheet and towel, you need to pay 15USD as we did it. Kitchen has really basic stuff like only two small knives so most probably you need to buy more stuff to make some meals. The bed was so uncomfortable and so small for 2 persons, you can literally feel metal/wires under the bed on your back. We asked the host to bring us something to have more comfortable bed but he was not able to do it. In the living room at night everyone through window can see you since cover for windows are almost transparent while in bedroom they were fine. During the day people can not see you in the living room so only at night because of reflection of light in the room. Internet was fine first two days after that it was terrible. You can not use youtube, Netflix etc because it was so slow. To also mention that apartment is on -1 floor.
During our stay we lost electricity for longer period of time that much that our food in fridge melted and was destroyed. We contact host about the electricity problem, at first he said that is was general cut of power but then we saw that building across us has electricity as well as restaurant near us and apartments above us then we connected host again and said these things and after a while a repairman came and fixed it. Host ignored the issue about our food being destroyed and he did not even apologise for it.
Good part of this apartment is that it very close to Taksim like 5min. from it and it is quiet except that you can hear almost everything from neighbour above you, probably bad sound isolation.
Last thing is that we believe that this apartment is so overpriced for what it offers but if you just want to be near Taksim and ignore all things above, then it is perfect place for you.
