I have read and reviewed several city and country guides recently and this was the most impressive of the bunch. It is extremely comprehensive and the summaries of the sights not to be missed were right on the money. As is not always the case, it was very easy to navigate around this guide and when places were mentioned they generally had a page number attached so they could be further researched easily.
There is a removable map at the back, although frankly this is a compact book and so it is probably no great hardship to carry around. There is a comprehensive index, but additionally a map where the 11 main areas of interest to a tourist are shown, and for each of these there is an additional map highlighting the major places of interest and indexing them. This is particularly helpful when planning a visit and to refer to when on foot in the area.
There is general information on planning a visit such as the ways of transferring from the two main airports to the centre and the price of transfers. I was going to say the only thing I found lacking was a metro map, but in fact I eventually found this on the removable map! I am usually rather dismissive of the information on accommodation in such guides as there is so much information on sites such as TripAdvisor that the additional information is largely superfluous. However, I have to say that I thought that what was included here was potentially quite helpful. Although I have not been to Rome since receiving this book so have not been able to test drive it, the information on restaurants and shopping looked useful.
Unlike some similar guides, the printing and production are quite good with colour pictures of reasonable quality throughout. Actually reading through it has rather rekindled my interest in Rome and as a result we plan to visit again soon. Rome is definitely a city where you should buy a dedicated guide rather than relying on a general country guide as there is so much there to see and being armed with this book will certainly enhance a visit.
