I grew up near San Francisco, and now live in the Boston area. I work as a middle school teacher and love my job. In my spare time I spend a lot of time reading, dancing, listening to music, and wandering around the pond near my house.
William showed me around Montmartre and some of the Marais. He had planned for us to take a bike tour around the neighborhoods, but was flexible when I told him I would rather we walk and take the metro.
He was very helpful in answering my questions about Paris...using the metro, tipping etiquette at a cafe, etc. William was very knowledgeable about the history of the areas and monuments we explored...sharing interesting anecdotes and answering my questions.
He's very knowledgeable, flexible, friendly, and has a nice sense of humor. Great qualities in a tour guide! Highly recommend!
