I was just thinking that you may like to have a visual of where everything is in Rome!
Most hotels will have complimentary maps, like this one, for their guests (our hotel had a nice one very similar to this), so if you plan on going to Rome you may not need to bring a map (or you can take one from your hotel home as a little souvenir).
I like this map better than most because it includes mini images of the bigger tourist spots and it includes the metro. Feel free to take a look at this page as you read my other posts about our travels throughout Rome. It will help you to get a better idea of where we went and how much walking was done each day!
