The hostel is perfectly located in the center of Žižkov, one of my favorite areas of Prague. The restaurant attached to the hostel was also amazing, everything we tried there was sooo good and the prices were very reasonable. The breakfast was also great and very filling.
However, I found the bed in the room extremely uncomfortable to the point that I had major trouble sleeping in it. I woke up after the first night with bad pain in my shoulder after not finding a comfortable position.
The facilities were great but the beds have to pull the grade down I'm afraid. It might just be a "me"-problem though, and as long as you are aware of the beds I would still recommend staying here. The restaurant alone is worth it!
