For the highest standard, The Capital Hotel is a wise choice, as it has 5 stars. A stay here allows you to access popular attractions, such as Parliament And Big Ben and Womens Library, on foot. 

There are good connections to the surrounding areas via Victoria Station. London is famous for Knightsbridge, Belgravia and Holland Park, which can all be reached on foot from this accommodation. 

You will not have to ever be too hot or cold, no matter what the weather in London is. Staying in one of the rooms will allow you to make use of a daily housekeeping service.
