I had a great time here. The bar in the hostel is a fantastic way to mingle with the other guests, as well as some locals who pop in. I was there every night meeting people to go explore the city with that night or the next day. I got great recommendations on how to spend my days with the super friendly staff. The bedroom I had and the bathrooms/showers were clean and well maintained. The hostel bar and the bar downstairs close around 2am, and there is live music down there, it didn't keep me awake but some may have trouble sleeping through it.
If you're in Denver for legal marijuana, the hostel basically shares a wall with a dispensary next door.
Oh, and get an absinthe shot.
