The oldest House in Bath is built in 1482. Now it's a cafe where there are nice coffee and bun. I didn't have a cup of coffee there because the cafe was closing when I arrived. However, I went to the cellar and visited.
It is a very old house and very narrow.. Recon that people in 1500s are very slim in order to pass through this tiny house. It is a good experience. However the cellar stinks a bit. :P
