Hotel On Phillips Sioux Falls.

Housed in the 1918 Sioux Falls National Bank building—once the tallest skyscraper in South Dakota—Hotel On Phillips masterfully repurposes its financial past into a stylish boutique stay. The historic architecture is front and center in the lobby, where the original 16-ton vault door and brass teller cages serve as striking design elements. This theme carries into The Treasury, a chic lounge tucked right inside the old bank vault that serves craft cocktails and small plates. The 90 rooms and suites offer modern comforts like premium bedding and streaming-ready TVs, while the mezzanine level features a library and fitness center. Located in the heart of downtown, the hotel puts the Washington Pavilion, local boutiques, and the scenic Falls Park all within easy walking distance.
