My friend and I stayed for a couple nights in the main bunk space. Everyone was very considerate, however the unavoidable noise/light leaks of people coming in and out at different times made it difficult to sleep. I used to stay in hostels while traveling when I was in my 20s, but now turn 30 I think my rest needs are more demanding. We changed our reservation and booked a private room with shared king bed upstairs, which was very comfortable. The accommodations in the shared space and the private room were clean and comfortable. The shared bathroom was impressively sparkling clean, very well maintained even during the time we stayed which was at complete occupancy. Easily the best part of the stay was meeting all the folk passing through Denver. It was nice to have a communal bar/lounge space where we could meet people in the morning while making breakfast, and in the evenings when we wanted to settle down for a drink. I would definitely choose the private room at Hostel Fish over any other hotel in Denver. The accommodations are fantastic for the price, with great hospitality and the added value of a traveler community within the hostel.
