I had the opportunity to take a summer course from Noel Riley Fitch and she is one of the most knowledgable people about this period of history in Paris and the artists who lived and created there.
The walks are great. They allowed me to get a sense of the city and how the locations tie together to form neighborhoods, even all these years later.
I highly recommend it to anyone interested in seeing where Hemingway drank, Stein kept her salon, and Joyce sold his books.
