Hotel St. Louis is now open, concluding a three-year effort from Restoration St. Louis to bring the historic Union Trust building downtown back to life.

Designed by famed architect Louis Sullivan, the 14-story Union Trust at 705 Olive Street had been largely vacant since 2013. Amy and Amrit Gill of Restoration St. Louis bought the 1893 structure in 2015 for $3.3 million and have since pumped $64.7 million into the renovation.

The street-level restaurant, Union 30, is now open, with Matt Birkenmeier of the late Quincy Street Bistro serving as chef.

Bookings have already started at the 140-room hotel, operating under the Autograph Collection Hotels by Marriott flag, with the next availability a week away. Each room features a vintage record player along with several albums with a St. Louis connection.

Two boutique hotels opening downtown, adding new life to dormant stretch of Olive Street Two downtown St. Louis boutique hotels will open along Olive Street later this year and could help spur a wave of building revivals in the Central Business District.

“We’re thrilled that we can be part of this vibrant renaissance occurring all around us, made all the more meaningful with the partnerships we’ve fostered with local businesses in terms of providing them a platform for visibility for their products at the hotel — and, really, what better way to unveil to the world, what a gem St. Louis truly is?” Amy Gill said in a statement.

The hotel’s rooftop bar will open early next year.

The hotel also includes 14 luxury apartments and a top floor, three-bedroom penthouse. The project received 20 years of property tax abatement from the St. Louis Board of Aldermen, with the last 10 years worth 50 percent of the value of improvements.
