We were a family of four with two small children on possibly the hottest day in Warsaw this year. Marta worked her magic and somehow it ended up being one of the best days of our month-long European trip. She is laid back and fun, the kids loved her, and she managed to show us Warsaw as it should be presented to the world. A city of incredible art, culture, history, strength and incredible resilience. Marta is very knowledgeable and full of life. Highly recommended
