My experience at Populus Denver was superb, the building itself, being the first carbon positive hotel ever, evokes a sense of calm and lends for a special experience. Great sleeping, quiet and superb bedding. You'll have an inspiring stay and if you pay attention to all the sustainability features, details on material used and biophilic design, then even more. You can even touch the exposed fly-ash concrete core (most carbon-friendly concrete) in the public areas and hallways of the hotel, lending it a special mix between nature driven and industrial minimalism. Water refill stations on each guest floor. If you are into design, you'll appreciate the efforts that were poured into this unique hotel. Located nicely on the side of downtown but not at all far from anything! Civic Park with Capitol, and museums are right across. Food and beverage venues are all recommended to visit with incredibly good food quality and value. Stellar Jay at the roof especially, try the hanger steak, pork chop or carpaccio, but also the vegetable options! The farmer salad at Pasque on the lobby level is superbly fresh and makes you instantly feel healthy - have a side of fries. :) I will for sure return!
