Yeah Cathy's right , Hotels are quite expensive anywhere near and around Kensington area which covers RAH , and obviously the further you go out from central London the Cheaper , but there are some unsavoury boroughs further out , so unless your gonna stay in central London averaging around £100 a night ( thats $160 abouts) Renting is a better idea pricewise and you can get some good large apartments for value
A Site that i know friends have used in the past is findaproperty.com it covers all London , but you want Central London and Recommend The Leafy Smart Suburbs of Notting Hill , Kensington , South Kensington , Knightbridge , Westminster , And My 2 Favourites Because of Price and Large Townhouses .... Earls Court And Pimlico ..... This is an Excellent site as you can pick price over quantity of bedrooms or area
This will give you an idea of whats available , Happy Browsing @ findaproperty.com
