I was a bit surprised by all the extremely positive reviews here for this hostel. While we didn't have a bad experience by any means, it definitely wasn't 5/5. It's true the breakfast is tasty and home made and definitely a cut above the usual hostel fare. However the private room we had was absolutely tiny, I can't remember how many times we bumped our heads on the bunks and the cupboards! The shared bathroom wasn't particularly clean and with the exception of Pablo, the staff were not particularly friendly. It's one of the few hostels where we never really felt at home.
Also, the morning that we arrived we had just got off a 30 hour bus from El Chalten and we were tired and cold. We arrived at the hostel at 7am to find all of the shutters down and the hostel in darkness. We rang the bell 4 times but no one came to the door. Eventually we left our bags in the doorway and went for a walk around Bariloche and to get some food/coffee only to find the whole town was still asleep. We came back to the hostel at 8am and were very glad to find some signs of life. However we were not made to feel particularly welcome and I got the impression we had inconvencied them with our early arrival (we didn't want to check-in, just leave our bags). I've never come across a hostel that was totally dead at 7am.
