The index, part of the latest Hotstats survey from TRI Hospitality Consulting, showed the GOPPAR value of London's hotel rooms in January 2010 to be worth £53.56, around 35 per cent above the closest comparable city, Paris, at £36.86.
Warsaw saw a GOPPAR figure of only £26.60, beating the levels achieved in Amsterdam £25.62, Berlin £20.86 and Munich £18.72.
Some of the lowest figures of the survey included Barcelona, which recorded a GOPPAR figure of £0.75. Much is thought to have stemmed from the decline in average room rates as well as fewer weekend leisure breaks and high yielding major conferences in the early months of January.
"As the main expenditure for hoteliers, the movement in payroll provides a good indication of the greater cost control measures being employed. Throughout 2009 London hoteliers have successfully managed this cost.
"It is also telling that those markets which have been able to reduce their level of payroll as a percentage of total revenue this month are the only cities in our sample which have benefited from a year-on-year increase in profitability," said TRI Hospitality Consulting managing director Jonathan Langston.
