Affluent and incredibly central, Kensington is a great base for exploring London on foot. Kensington Gardens and Hyde Park are on your doorstep and so are the Victoria and Albert, Science, and Natural History Museums. The streets are attractive and well maintained (grand, white stucco facades aplenty) and your neighbours will be a wealthy, conservative set. Lots of positives but probably not the place to let your hair down.
