I went to London in 2003 to meet someone who used to post here and deliver a couple of lambs to the Watchtower House for Silentlambs.
My hotel was on Cromwell Road in Kensington - ideal location! I was within a couple of blocks of two supermarkets, a laundromat (with drop-off service that cost very little more than do-it-yourself), an Italian restaurant and several other decent restaurants, a "tube" (underground/subway) station, and the city bus, not to mention the British Museum and the Museum of Natural History. Harrod's was a 20-30 minute walk from my hotel. I recommend all of these. In front of Harrod's, you can get tickets for a tour bus that takes you all around the city. There's even a boat ride down the Thames included.
Mr and Mrs. nightwarrior met us and took us to a pub and Covent Garden. They were a lot of fun and very kind and generous to us.
We took a train to Paris through the chunnel. It was great to see some of the English and French countryside out the window. The food and service were excellent.
I'm sorry I didn't have time to take a tour of the Lakes District. That'll be on my next trip.
I just want to go back. I LOVED it!
