My husband and I just spent a week in Sebastien's apartment. Located in Le Marais, the neighborhood has everything one could want. It is centrally located, and the apartment is very close to a Metro stop. Sebastien was a fabulous host. He got tickets to a jammed museum exhibition that I was able to attend at a time that worked for me and with no time spent waiting in line to get in. He was very helpful with other matters as well. He produced a compendium of helpful information in a book for guests that was very useful. And the apartment is comfortable and adorable. We had a wonderful stay. I would highly recommend his apartment.
