Annabel was our tour guide. Grandmother and a 13 year old boy interested in architecture. We were the only ones signed up so we essentially had a private tour. It was advertised as 3 hours and turned into 3 and a half. We were taken into both public and private spaces. Annabel knew her subject….dates, styles, the people behind the money to build the skyscrapers, historical anecdotes from the Rockefeller to Leona Helmsley, and more. She had the capability to engage both Grandma and Grandson. A perfect treat.
