Walk to either of the local train stations which is five mins max either way. Hop on the train to Victoria which takes about 16 mins, push my way through hoardes of commuters and tourists, swearing as I go and kicking several of those bloody trolley things* (*depends how busy it gets and how many gormless morons are in front of me!). Hope on the Tube to Sloane Square ("darling sweetie darling.."..) walk to work from there which takes about ten mins. Easy.
Have commuted on the bike which takes about 40 mins door to door but the route takes me through two really REALLY nasty areas in regards to trucks, lorries and buses etc.... I don't think it's worth putting my life on the line. Looking into alternative routes.
