Definitely a clean apartment, close to public transportation and the city center. I used to walk every day to Galata Port and Taksim. I would say the price I paid for eight nights was acceptable.
The only significant issue with the whole apartment is that the walls are too slim, and you can hear everything from other flats, when someone is cleaning, and when a kid is crying at night.
PS: don't forget that you have to take stairs or uphills to reach the flat, and that's the beauty of Istanbul ;)
