Excellent pocket size book,has some good pointers but also a couple of facts were wrong. Check the bus time tables yourself as I waited 30mins for the wrong bus.and some timings were out of date.Other wise a really handy little book.
I usually buy Top 10 Guides for our weekend trips, but this city Guide Lonely Planet was perfect. It was a recent edition, with up to date information, and highlighted the best that Reykjavik had to offer. Very happy with my purchase.
