The apartment itself is very clean, and just as described and shown in the pictures.
There are shops and restaurants right on the doorstep, and it's only a 5-10 minute walk to the Blue Mosque, the Hagia Sofia, and a tonne of other amazing landmarks.
Yakup was an incredible host, checking up on us with offers of assistance, and even letting us stay past checkout on our final day to make things as easy as possible for us.
