Spent only 3/7 nights in this aparts and leave it by myself.
Aparts are located at very dangerous and poor region of Istanbul. Every our fellow travelers from our friends to taxi drivers tells the same. It's very dirty on the street, bad smell (people carve shellfish in cellars) , a lot of children are shouting loudly at night, it was such feelings that I'm not in Istanbul, but in Bangladesh.
I think it's not just uncomfortable but unsafety to live in such accommodations especially with wife/girlfriend or children. I have wrote a latter to Yasmin with the request to cancel my reservation but she defused it. My recommendation is to add information about environment around in your add.
