Łukasz was PERFECT for us. He was knowledgeable, informative, organized, courteous, and funny (when appropriate). He clearly communicated accurate information about history and current events, and also shared his opinion when we asked. He adapted the tour to our interests. He walked at our pace (we're a little older and have to move just a little slower). He included both of us (unlike some guides we've used who speak only to the man and ignore the woman). He has a GREAT sense of humor and shared personal anecdotes. Very touching stories. We thought he made Warsaw come alive! We HIGHLY recommend his tour!
