Pros: Great location and authentic to Turkish cozy style. It's a very 'homey' experience and good for remote work - good view from behind the table to the Bosphorus and also lots of light in the apartment. The host has left for you to use all of her things that one needs at home, such as spices, teas, make-up remover etc. Also it has two bedrooms that are nicely separated so you can get privacy easily when renting it together with a friend. All good with warm water also. The host is very responsive.
Cons: the apartment was rather cold, even when we turned more heat on. Also though the host was very responsive and provided everything when we asked, then there were certain things that weren't there when we got there: shampoos (though they were listed in airbnb), more toilet paper (we only had one roll waiting there...), coffee. There was also a little crack in the bathroom wall/ceiling that let the rain in.
Consider: area is 'hilly', lots of stairs to climb to get somewhere
