The apartment was great, we enjoyed staying there very much. The view from the livingroom is beautiful.
On the plus side: beautiful view, close to Istiklal street, authentic neighborhood (we arrived on Sunday evening and found a food market stretching down the road).
On the minus side: incredibly squeaky bed and not very comfortable, the shower drain was clogged... and the last minus, which for us was notable was that you get only one set of keys. You cannot shut the door without the key, meaning if you need to go out alone you either lock your partner/friend inside (very unsafe), or leave the door open. We asked the owners for a second set, but they said that they don’t have them.
Also, the apartment is located on the 5th floor (hence the nice view) and has a steep, beautiful, winding staircase. If you have luggage or a child with a buggy, this might not be the best choice
