Hilton's Doubletree brand will add two more London hotels to its portfolio this summer.
DoubleTree by Hilton London Hyde Park and DoubleTree by Hilton London Ealing will both open under franchise agreements with Westmont Hospitality following extensive refurbishments totalling £20 million.
The properties bring the total number of Doubletree hotels in the capital to nine.
Patrick Fitzgibbon, senior vice president, development, Europe & Africa for Hilton Worldwide, said: "These two new properties complement the strength of our long-established Hilton Hotels & Resorts presence, whereby this year we are celebrating the 50th anniversary of the landmark London Hilton on Park Lane."
The 228-room Hyde Park hotel, which is located on Bayswater Road opposite Kensington Gardens, has a 24-hour fitness centre and, from September, a stand-alone restaurant with a terrace overlooking Hyde Park.
The Ealing property has 189 rooms and six meeting spaces that accommodate up to 240 people in a banquet style.
In March, the Doubletree brand announced three more UK hotels - in Bristol, Edinburgh and Nottingham - were to join the portfolio.
