Free tours - Trips, Economy, Leisure

In some cities, like Amsterdam, Berlin, Dublin, London, París, Madrid, Hamburg, and so on, you can find the "Sandeman's new europe". They wear a red T-shirt, and they make a free tour around the city, maybe at the end thoy ask for something, but it is up to you to give them, 2€, 3€, 4€.... or nothing at all.

here you can find the info http://www.neweuropetours.eu/

I hope is useful =)
