This was my first time a.) visiting Denver and b.) staying in a hostel and c.) I could not have liked it any more than I did! The staff was helpful and welcoming, the decor and ambiance is unique and inspiring, and the connections you make with the other guests are electric! I could not have had a better first exposure to staying at a hostel. The location of Hostel Fish is also perfect - in Lower Downtown (LoDo) right near the Coors Field so there are a ton of cool bars to check out (like The Retro Room and Sidecar) or great places to eat (Ignite Burger and you'll definitely want to check out brunch and boozey breakfast cocktails at Snooze). Or if you feel so inclined to stay in, there's a small kitchen and bar in the hostel (with decent prices) so you don't even have to take off your pjs! I highly recommend staying at Hostel Fish for your Denver travels.
Comfortable bed, clean bathrooms, friendly, helpful staff and patrons, quirky and interesting decor. My wife and I stayed in a private room and would definitely return here if we find ourselves in Denver again. People moving about at night were a little noisey, but once the thermostat fan kicked on i didn't notice it anymore and fell asleep.
This is by far the nicest hostel I have ever slept in, down comforters and soft sheets were a real bonus. Very friendly staff and patrons. Would definitely recommend to anyone visiting Denver
