One of the most unique finds in London. It's basically a house of the most eclectic museum-worthy collections. No sterile museum-feel here. It's corny, but you will feel "at one" with the art.
Cons: It's highly suggested to go to this museum with a guide. Everything from the architecture to the organisation has meaning. Every piece has a fascinating history. Find an art historian friend and go!
