The London Fire Brigade (LFB) said that 20 fire engines and about 125 firefighters were involved in tackling the blaze on Chiltern Street in Marylebone on Friday.
In an earlier statement, the LFB said: “There is a fire in ducting which leads from the ground floor to the roof of the four-storey hotel with a restaurant on the ground floor.
The unnamed firefighter told the PA news agency: “It’s (the fire) completely under control in there now, but the hotel is probably going to need a large refurbishment.
Guy Fischman, 23, from Richmond, south-west London, was leaving his workplace near Bond Street when he said he saw “the whole street full of smoke”.
Then, at around 5pm, when he left his workplace, he said the road was closed off because “there were loads more fire engines” with large hoses and a crane.
