A boutique Beacon Hill hotel that underwent a series of upgrades under Related Beal’s ownership sold for $57 million to a private equity investor.

The 65-room Whitney at 170 Charles St. was rebranded in 2019 following an expansion and renovation project. Related Beal acquired the property in 2015 for $40 million. The renovations, designed by Boston-based architects Hacin and completed in 2019, included a new lobby and restaurant.

The buyer, Egeria Real Estate Boston, is an affiliate of private equity firm Egeria which has offices in the Netherlands, Germany, Switzerland and Boston. The new owners are not planning any major changes in management or operations, Egeria said in a statement.

“We are working with the seller on a smooth transition and look forward to preserving the Whitney’s traditions in collaboration with the surrounding community,” the firm stated.

The hotel investment sales market hit pause after COVID-19 disrupted business and leisure travel. Boston was one of the nation’s hardest-hit markets in declining room rates and occupancy, according to industry research, before rebounding strongly in 2023.
