Natalie's 2.5 hour 'Discover Berlin' walking tour was a brilliant way to get a feel for the city, and her knowledge and passion for the city shine through. Her engaging style is great and encourages questions, ensuring you get the most out of your visit.
Berlin was so much more than I expected and I think that was down to Walkabout Tours. I'd highly recommend them both for tours and itinerary planning if you want to get the most out of your stay, and experience the city like a local.
