The 70-bedroom 5-star property, which remained owned by Davis after the rest of the Von Essen estate went into administration, was placed into administration itself at the end of July.
It has been run by administrators for Ernst & Young while property agents Christie & Co searched for a new owner.
On Friday, it was announced that the hotel, which includes the Patrisey restaurant, a spa and fitness suites, had been bought by a private buyer for around £20m.
Angela Swarbrick, joint administrator at Ernst & Young, said: “We are very pleased to announce the sale of Hotel Verta, helping to safeguard over 75 jobs and the future of this premium central London hotel.”
Christie & Co's director of London Hotels David Creamore, said there had been a 'tremendous level' of interest from potential investors in the UK and abroad.
"The new owners have acquired a superb and rare opportunity to gain a foothold in London’s hotel marketplace. Its situation near the London Heliport, its views over the Thames and its commitment to style and luxury make Hotel Verta one of the unique hotel experiences in the capital,” he said.
It has not yet been revealed who the new owner of Hotel Verta is, or if there are plans to change the focus of the luxury hotel.
Fifteen of the 26 Von Essen hotels which went into administration in April have now been sold, with Nigel Chapman's Halcyon Hotels & Resorts the most recent company to take over seven of the properties. Eleven, including Cliveden and The Royal Crescent in Bath are yet to find new owners.
