I spent 9 days in London last September. That was marvellous to see what this city has to offer. My hotel (The Royal National Hotel) was on Russell Square, only about 5 minutes from the British Museum who's one of the most visiting and beautiful museum on earth. I took The Tube (metro in London language)only once for Kensington to visit the Victoria & Albert Museum and the National History Museum. If you want to see Stonehenge, take a sightseeing tour that comprises a visit to Windsor Castle and to the Salisbury Cathedral for about 50 pounds. It takes a complete day to visit these 3 lovely places. And if you already went many times in London, don't forget the London Transportation Museum, the Bank of England Museum, and the very small museum of John Soane. Ah London ! I won't forget you
