Mp3 tours are a great way to get to know a city. These mp3 tours have many advantages over an actual guided tour: you can take them at your own pace, stopping for tapas along the way if you want or listening to the tour over a number of days. Slow walkers can take their time with these tours, while those in a hurry can skip the bits they aren't interested in.
