I stayed at mustafa's women's dorms for approximately 2 weeks , very safe building with cameras everywhere , the floors and common places are cleaned regularly, I didn't have the access to WiFi so I don't know if free WiFi exsist or no , the building has 5 floors ( without elevator ) , the location is amazing 2 min from marmaray Station and a bunch of other buses and minibuses , rooms are really small , liveable but small , do not recommend for clostrophobic people.
kitchenware aren't provided, if you are planing to cook , also you have to pay 20 lira for laundry.
finally, host mustafa was really kind , he speaks English very well , as his wife funda was helpful too .
mustafa accepted my last minute extension of stay .
I knew a lot of kind and helpful girls there , I felt home in a foreign country and this is a big plus .
