The apartment is large and looks like the photos. There are some issues you need to keep in mind when renting the apartment:
1. The apartment is in a noisy neighborhood with a club right below it. If you open the windows, which you will need to do since there is no AC, you will hear noise pretty much the whole day and night.
2. There is no AC which is fine if it's not too hot.
3. There is no elevator and the apartment is on the 4th floor.
4. The living room has no table to put anything on the bedroom only has one closet for clothes.
Other than these issues, the location of the apartment is very central about 15 minutes by walking to Taksim and a few minutes to the metro. The internet is stable and fast and the kitchen is fairly complete. Hacer is a good host and will try to fix any problems you have.
