The western hotel

once owned by Mike Bosco who also owned Hotel Denver, was initially called the Bosco Rooms until the 1920s. It was considered a place for working-class people to stay, providing simple accommodations for local workers. Built-in stages starting in 1888, it had a saloon and restaurant initially, with additional renovations done between 1904 and 1907. In 1912, a second story was added. Before prohibition in 1916, the hotel was known for being a spot where women in Glenwood's red light district worked. In 1939, Bosco sold the hotel to John and Ida Toniolli for $5,000.

John worked as a miner, but Ida wanted to protect his health, so she convinced him to buy the hotel. The business thrived during the 1940s and 1950s. The hotel hosted friends and family of veterans recovering at the US Naval Convalescent Hospital during World War II. In 1953, construction workers building a new bridge over the Colorado River stayed at the hotel. The Toniollis expanded and renovated the hotel, building a two-story addition in 1945 and remodeling the Cooper Avenue facade in 1951.
