The night I stayed here, a bar party raged one floor beneath me until 2 am. It was not clear to me that the bar would a) be so close to my bed and b) not observe any kind of quiet hours. I don't know how often this is a problem as very few reviews mention it, but for those few nights when it is an issue, it is QUITE an issue.
If not for being unable to sleep through the thumping bass and loud singalong, I would have really loved this hostel. Check-in was easy (though I could not find anyone at the desk when I wanted to find out when the party would end) and they held my bags for me until I was ready to leave Denver. My bed was comfortable and very decently private in a 6 bedroom. The bathroom was clean. And the decor is gorgeous!
In my opinion, this will be a great stay at a wonderful location if Hostel Fish decides to prioritize guests' ability to rest at night over carrying on the party of the surrounding bars and breweries.
