Both of my parents are retired history professors so for my mom this was her must do. We did the Shop Life tour with Melissa which was very interesting, well planned and a great layout. It was a little noisy with tours going on above our heads since we were on the first floor. I just decided it was probably exactly what it was like when 22 families lived in the building. Wished we had more time to take other tours. Would take another tour on my next trip to NYC.
