We did 3 tours (1 in Salem, 2 in Boston) and this one was BY FAR the best one and I highly recommend it as a tour to take early on in your trip. They were very informative, easy to hear/understand, explained things well for any age group, and answered questions thoroughly. At the end of the tour, they gave recommendations for nearby food options that were well-informed (delicious). We got to see a lot and learn a lot about the origins of Boston, famous historical events, significant buildings, etc. and is a great starting point for deciding which parts of the city to dive deeper into later. I would even repeat this tour in the future with other travel mates - worth every penny. :)
