10% increase in November - Deloitte
There was a "dramatic" increase of 10% in revPAR (revenue per available room) in London hotels in November compared to the previous month.
Hotel consultants said the figures from sister company STR Global, showed London was "leading the recovery in European hotel performance".
The rise in revPAR come after "13 consecutive months of decline", Deloitte said.
Marvin Rust, its hospitality managing partner, said: "November has been a great month for the capital.
"Hoteliers reported stronger conference and meetings business over the previous year when demand was suppressed in the wake of the Lehman Brothers collapse and the other stresses in financial markets worldwide.
"The leisure market also remained buoyant with more events this year such as the ATP World Tour Tennis Finals held from 22-29 November at The O2.
"Soft exchange rates versus the pound continue to act as a magnet for tourists making the capital around 30% less expensive than this time last year."
The STR Global figures showed that occupancy in London in November was 85.8% while average room rate (ARR) was £138 and revPAR £119.
For the UK as a whole, occupancy was 72.8%, ARR £92 and revPAR £67, a slight, 0.6% rise on October.
Edinburgh was the only other UK city to show a rise in revPAR.
The Scottish capital enjoyed a 2% over October with a revPAR of £59, occupancy of 75.2% and ARR of £78.
Other cities, among them Liverpool, Manchester, Birmingham, Bristol, Cardiff, Leeds and Glasgow all saw revPAR fall.
Among the biggest revPAR drops were Gatwick Airport where it fell 19.2% and Liverpool city where it slumped 25.6%.
