I was unable to reach anyone at the front desk for several hour prior to arrival to inquire about local airport transportation, which was stressful--we were arriving after midnight and had never visited Denver. Was hoping to take the light rail, but ended up in an $80 taxi instead. Other than that, we had an excellent experience. Staff was lovely and helpful, the breakfast cart attendant could not have been nicer (so peppy and helpful at 7am!), the lobby is warm and inviting--my daughter and I grabbed lunch takeout and ate at the table there--lovely. Lots of towels for two people. It's a block from Union Station and walkable to several great restaurants. (Shout-out to Tupelo Honey--scrumptious food and fantastic service.)
Wish our stay was longer, but we'll definitely stay at Hotel Indigo again.
