This map covers the following areas: Main London City Map 1:20,000 London Underground Map - London Tube MapThe Most Useful Map We just returned from nine days in London and I have to say that this map is the most useful thing we brought with us. It's laminated so that it didn't get ratty like our tube map. (There is also has a tiny tube map on it.) It was easy to slip in the front pocket of my swing pouch and it's small enough so that we didn't look so much like tourists unfolding a giant map when we had to consult it. The map had all the tiny streets in Covent Garden, the City and other areas, so I'm not sure what another reviewer had a problem with. As for covering all of London, maybe you'd need a different map if you were visiting the outer neighborhoods, but for all of the major and minor tourist attractions, this was more than adequate. It's like expecting a tourist map of New York City to cover the outer reaches of Queens and Staten Island. They're technically New York City but the majority of attractions are in Manhattan and the nearest parts of the boroughs. I would definitely buy this map again and I have already purchased a Streetwise Paris map for our upcoming visit.
