I stayed at Ember during its second month of opening and highly recommend it to travelers hitting Denver. I've frequented countless hostels and this one had all of my favorite amenities (especially as an semi-introvert): Private bunks with personal outlets and curtains, numerous cozy nooks to curl up with a book, indoor AND outdoor fireplaces, eye-pleasing decor, great key card access, friendly staff, fun social parties for when you feel like making friends, a huge jacuzzi open all night, extremely clean spaces all around, and a five minute Uber ride to the city action. I would stay here again anytime I'm in town. 5 Stars :)
