We did a Viator tour - private tour for the four of us - Private Antigua Excursion. The driver was excellent and the tour guide was top notch - Eduardo. He knew so much about the history and geography, economics, architecture of the area. He stopped us at a local market so we could buy a local beer to try out. He also stopped at a really neat coffee and bake shop for us to have some super smooth guatemalan coffee and treats. They sold us the coffee too! He walked us all over town to tour beautiful old churches and buildings and town squares. Highly recommend!! His Dad Hector is also a tour guide and supposed to be great too!
