Station Manager Lee Walker, who was at the scene, he said:
"When I arrived there were flames coming out of the first and second floor windows of the property, the roof was also well alight. Fire crews worked hard to extinguish the fire. Motorists were advised to avoid the area as Prince of Wales Road was closed to traffic."
The Brigade was called at 1932 and was under control by 2217. Fire crews from Kentish Town, West Hampstead, Paddington, Soho, North Kensington fire stations were at the scene.
The cause of the fire is under investigation.
