I recently stayed at AZ Hostel and was really disappointed. Lonely Planet described it in their latest Central Europe guidebook as homely, but I would describe it as dowdy and cold. The double my partner and I stayed in was spartan to say the least. The room was four ugly concrete walls, a bed, table and desk. There was no lamp, mirror or bin and the curtains did not cover the window adequately.
It was 1300CK for the room for the one night we stayed, which I think was a bit steep. Unlike other hostels we've stayed in, despite advertising a kitchen, it did not have a kitchen. At best, the "kitchen" could be described as a tea room i.e. you could boil water, but you could not cook a meal here.
Unfortunately, the only good thing I can say about this hostel was that the location is excellent, only about ten minutes walk from the Hlavi Nadrazi and is about five minutes walk to Wenceslas Square.
