Very nice and cozy apartment. It is not large, there is space for a bed and a table with a freedge under it, but the bed is very comfortable. It also has a balcony with an amazing view.
Very clean, the owner left me instructions on how to enter it. The location is excellent, you can walk to the main attractions in Istanbul (which I did) or you can easily go to the tram station to go wherever you want. The blanket is very warm, which whas important because it was very cold in Istanbul when I was there.
The shower is amazing, it is really good!
The only negative aspect I can think of is that you have to climb some stairs in the building to reach the apartment. If you have a heavy bag, that may be a problem. But, if you, like me, travel with a backpack only, it is not a problem at all.
I definitively recommend the place.
