I had a couple in the car last night that told me about these, they downloaded them at home in France (in French, they are also available in many other languages)
They then put them on their MP3 player and where guided around Dublin for the few days of their visit. They said they were fantastic............ and even better, they're FREE!
If any of you know of other cities that offer this service I'd love to here about them, they sound like a great way to learn more about the cities you visit.
And now the site to clear your brain of my crap..........
