I stayed in this hostel for 4 nights in the 25 beds dorm and I enjoyed it very much.
Of course this is not a place for people who seek luxury, it is basic and you receive what you pay for.
The location is very close to Ayasofia and the Blue Mosque, Actually it is just behind Ayasofia and I attached a picture for Ayasofia that was taken from the balcony of our dorm.
I made good friends while staying in this hostel thanks to the friendly atmosphere of the hostel.
There is only one issue, like i said i stayed at the 25 beds dorm, it is not a good room if you want to stay in the winter time, 1st: it is cold, 2nd: when it rains it is really loud. But for my experience, it was very good.
