The 692-bedroom hotel has been rebranded from the Thistle Marble Arch. It joins sister hotel the 239-bedroom Amba Charing Cross, which opened a year ago today.
Located overlooking Oxford Street, the hotel offers bedrooms with an average size of 33 sq m, Hypnos beds, Nespresso coffee machines and walk in rainfall showers.
It also prides itself on a strong technology offer with USB sockets next to the beds, free super-fast Wi-Fi throughout the hotel, and a tablet and smart TVs in every room.
There are no room service charges for the delivery of food to the bedrooms, with guests paying the same price for a meal as they would in the Grill restaurant, the bar or lounge.
Belinda Atkins, chief executive of Amba Hotels, said: "We're hugely excited to be extending our Amba Hotels portfolio with such an iconic London hotel venue, known throughout the world. This has been one of London's biggest hotel renovation projects in recent years - and the work that has gone into the new Amba Hotel Marble Arch is further demonstration of our commitment to listen to guests and design every detail of our hotels based on their input and feedback."
Amba is one of five brands operated by GLH alongside the Clermont, Every, Thistle and Thistle Express. The luxury Clermont brand is yet to launch, although the Royal Horseguards was originally earmarked to be rebranded as the Clermont hotel in 2014.
Further hotels with the existing GLH portfolio are expected to be rebranded to Amba in due course.
