Absolutely awful hostel, worst I've ever stayed at and in immense pain because of them. Was only there for 2 nights, I had requested a bottom bunk due to health issues (I have chronic fatigue syndrome) and they never responded and gave me a top bunk. The bed I did get was atrocious, there was a massive dip in the mattress which really messed up my back. Following that I asked for an extra pillow to help with back issues and the receptionist said that I will have to speak to housekeeping the next day around 10:30, I couldn't believe how unprofessional it was, I had one day in Vienna so I absolutely didn't have time to hang around waiting for house cleaning. That day I get home, hoping to find the pillow has been left for me but instead I come back to find that they have taken the quilt cover off my blanket and just left it there. Being exhausted I didnt have the energy to put it back on and quite frankly I shouldn't have to. I don't have a single positive thing to say for this hostel, was really bad service and the amount of pain the bed caused me is disgusting. Never stay here.
