I had previously used Frommer's 24 Great Walks in Paris and was very pleased with the series so I decided to purchase one for Rome. Again, Frommer's provides excellent self-guided walking tours of the cities most notable neighborhoods along with a few areas that are off the typical tourist itineraries but are still very noteworthy and interesting. Frommer's provides concise commentary and good suggestions of how to view various museums and sites. With each itinerary about 1 mile and taking about 2-3 hours, these are all great little tours to avoid the "herding" of traditional group tours. These are good for first time and repeat visitors of the city. I did notice that there is a fair level of repeat in some of the itineraries though so you may want to adjust certain tours before your leave. Also, you'll want to make sure you have a detailed map of Rome to use in conjunction with this guide as only the major streets are printed on the maps. I actually forgot a detailed map one day and fared just fine but it would have been helpful to have had the more detailed map just to be sure I was headed in the right direction.
