Arguably the hippest neighborhood in Denver, RiNo, for River North, is the ever-evolving arts and culture district just to the north of downtown. First came the artists’ lofts and galleries, then the shops and restaurants, and now, finally, boutique hotels like the Catbird. This is as modern as they come in the Mile High City, a hotel that, strange as it sounds, is perhaps most reminiscent of Dutch boutique hospitality, thanks to a pervasive modernist influence and an approach that craftily packs a surplus of useful comforts into studio- and loft-sized spaces. It’s geared as much towards long stays as to typical two-night tourist trips, and offers services that feel almost residential: a low-key rooftop terrace bar and lounge, a fitness center with Peloton bikes, and the all-day Catbird Kitchen + Marketplace, which functions as a café, breakfast room, bar, restaurant, and co-working space all rolled into one. And next door is a hidden gem in a rather different style — the circa-1890 Klee House is a four-bedroom residence in weathered red brick whose interiors have been given a stylish postmodern makeover, and which is suited for up to eight guests, complete with a private kitchen.
