I work in the concert touring industry, so naturally I do a lot of traveling for my work, and I enjoy it. I love being a tourist when time permits, and like to see landmarks, monuments, and other things that make a city famous, even if it's a little predictable.
The tour was an excellent, very moving experience, and led by a very knowledgeable guide.
My only complaint - the Viator directions to meet the tour. After booking, a separate window opened with a map for a meeting spot, but the voucher had different instructions, and almost caused me to miss the trip
