Such a wonderful tour. Cecilia was a lovely guide. She intertwined culture, food, customs, history and drink in a wonderful way. We learned about the good, the bad, the ugly - and the very tasty! I would highly recommend doing this as soon as possible once arriving in Lisboa, as it gives a great perspective of the city and helps you plan what to do next. I think this tour attracts really cool people as well. Loved the conversations with other people. Got the scoop on what to do in Ireland on a future trip (great bonus!)
Be sure to be ready to walk and be outdoors. Wear comfortable shoes and appropriate clothing for the season. We visited in late May, so shorts, sunglasses and flip flops were perfect.
