Signed up for the 2 hour free walking tour of Lisbon on their website. Was sent a whatsapp message the night before to confirm our attendance. Meeting instructions were very clear. The tour size was about 12 people. The guide was super knowledgeable, and made everything sound really interesting. I'm not really into history, but I do like to learn about a new city when I arrive, and 2 1/2 hours on this tour was absolutely perfect. The city is very hilly, but we actually met at the highest point, and most of the walking from then on was all down hill, with a lot of breaks where the guide talks. At the end he also sent us a list of recommendations for local restaurants and bars. This is a perfect way to get acquainted with Lisbon. The guides work for tips, he mentioned 15 euros is the average but you could give whatever you want. I gave 20 since I thought it was so well worth it! read more
