Sandemans New Europe is an organisation that organises free guided walking tours all over Europe in different cities. It is free but eventually everyone gives the guide a tip. It takes 3hours and a half and the guide tells a lot of stories about the history and culture of the city. It was really interesting and our guide - Robbie - was great. I did this tour with a girl from New Zealand that I met on the website: couchsurfing. Afterwards we had a drink with other people from the website. It was a great day.
