They are an enjoyable read with great photographs plus maps and plans of all the places you can visit.  They have recommendations on where to stay, where and what to eat, and also what the best items to buy are from the region.  In addition you can find all the info you need on transportation in the area - i.e buses, trams/trains, metros, and taxis.
