The room was clean and very nice. Like on the photos. You don't need to take so much clothes with you, because there is also a washing machine. Clothes are cheap and nice in Istanbul. :) You have every dish you need, even a dishwasher.
You'll have a huge balcony. We had every morning our coffee there. (Starbucks is just 2 minutes by feet)
In the area there are a lot of small supermarkets and 5 min by feet you have also a BIM. (Bigger market)
In the building you have a gym, indoor pool, sauna and steam bath.
There is also a garage for parking.
Distance to Taksim by feet 20-25 minutes and to İstiklal about 10-15 minutes. If you don't want to walk just stop a taxi. It is 40 TL (2€) to Taksim or Galata. In the Taxi it will show 20-30 TL, but in Istanbul the minimum price (get in get out) is 40 TL. So there is no need for discussion with the driver, that's from the government. :)
