I took the old girl to http://www.millenniumhotels.co.uk/millenniummayfair/?s_kwcid=TC|14121|millennium%20hotel%20london%20mayfair||S|e|17590449613 for our 40th wedding aniversary. It was just about a £15 taxi ride from the Royal Albert Hall. We stayed 4 nights. Breakfast was good and the one occasion we had dinner it was superb. Handy for the shows and some good restaurants within walking distance.
