Knightsbridge and Chelsea are two upscale neighborhoods located in southwest London. They are home to London’s most expensive homes and some of the streets have the highest density of millionaires in the world. Knightsbridge is known for the famous department store Harrods, but of course this isn't where the average Londoner comes to shop. Local fashionistas prefer nearby department store Harvey Nichols. Tourists come to Knightsbridge to visit three of the best museums in the world, and for Hyde Park. Chelsea is a lovely neighborhood where you can saunter past beautiful, renovated Victorian buildings, and visit the Saatchi Gallery.
