The 184-bedroom Mercure London Heathrow hotel has opened following a multi-million pound, six-month refurbishment and rebranding from a Comfort hotel.
Crimson Hotels is the owner and operator of the property, following the signing of a franchise agreement with Accor.
Featuring design elements reflecting its location, such as a wall made from leather luggage, the hotel includes Borders restaurant and bar, a Costa coffee shop, gym and extensive meeting facilities.
Jonathan Sheard, senior vice-president operations, luxury, upscale and midscale hotels, Accor UK & Ireland said: "The hotel's new look reflects our commitment to providing excellent facilities in each hotel across the country."
Crimson is the owner, operator and developer of 13 branded hotels in London, Portgual and Dubai, through agreements with Accor, Intercontinental Hotels Group, Choice Hotels, Wyndham Hotels and Resorts and Hilton Worldwide.
Mercure, which is one of 14 brands owned by Accor, comprises 700 hotels in 52 countries.
