The Streetwise London map is very convenient if you limit yourself to central London and only need to find important attractions and/or streets of major or moderate significance. But many smaller streets in central London are NOT even named on the map and are not listed in the index. This was definitely a problem for me in finding smaller hotels, restaurants, etc. and lesser tourist attractions. In addition, the map includes some decent subway information, but nothing about buses. The reason for these inadequacies appears to be that the map is not detailed enough for there to be room to label the smaller streets and lesser tourist attractions. In summary, I suspect that this map will work better for first-time visitors than for repeat visitors.

I ordered "Streetwise London" based on reviews such as "must have" and "don't go without it."
Luckily, I also ordered "The London Mapguide" because I found "Streetwise London" a big disappointment... The map is from the early '90s. The size is handy, but too small to legibly show enough detail to be much use.
"The London Mapguide," for about $1 more, shows tube routes and stations, bus routes, and lots of other useful detail and it will also fit in a big pocket.

A week in London, and this map was with me on every outing. The Streetwise Map is a great help in navigating Central London, but if you want to go beyond "Zone One" on the London Bus and Underground system, this map will be of no help at all.

Could stand to cover a bit more area. Don't plan on using it outside the center of London.

During our eight days in London, this map was our constant guide. Laminated in plastic, and fan folded, like an accordian, I carried it in my hip pocket. I could whip it out and open it in two seconds. My 51 year old eyes had no trouble reading the print. All of the information you need for locating and navigating the Underground is also included on the map. When finished with the map, you can snap it shut, and tuck it back in your pocket, again in about two seconds. We developed true affection for this helpful map, and it is now among our keepsakes from the trip.
