It is small enough to fit in a pocket, but is packed with information and colour photos. Lots of recommendations for places to eat or visit and useful tips on things like parking on the island.
The front and back covers include fold-out maps which are usable, even given the small size. The layout gives you a good flavour of the island and makes for an easy read. I looked at similar guides and this seems to be the most recent and up-to-date.
It starts with Top 10 attractions and a perfect day out - then goes on to chapters covering : History, Where to go, What to do, Eating out, Tips, Hotels and a useful Index.
I couldn't fault this and it is great value - recommended.
