Staff at this hostel were fantastic especially JayPee. Very helpful and happy! The rooms can be very noisy though. Next to a main road, railway line and under the airport means you should bring some ear plugs or be hopeful your room is on the other side of the building. Great common area garden for meeting people.
The hostel is ideally suited to group bookings. For individuals it is not the best place to stay as there is not really a communal feel to the communal areas. It is not easy to meet people. That being said it is secure and clean. It might be wise to add more power points in rooms as only bunks on the floor have them.
This hostel has just opened and the owners have put a lot of effort into making it a genuine reflection of Turkish style both decoratively and the staffs open and welcoming attitude. A really comfortable place to stay that I would highly recommend.
The general decor of the hostel is poor and rundown. The other hostels we stayed at in Japan were more modern. A bit of paint, some art on the walls and a new kitchen/layout to give more space in the common area would be a good idea. Check out Bonsai guesthouse in Osaka that i9s available at a cheaper price but is far superior in facilities. Beds are very uncomfortable. Get some matresses! The staff on site were great.
