We stayed at Sebastien's top floor apartment for over a week and had a great time. The apartment is ideally located in Le Marais and the apartment has all the amenities that we could have possibly needed. The apartment was clean when we arrived and ready for use. Sebastien met us (even though we were slightly late) when we arrived, was always available if we needed anything, and generally a terrific host. We would definitely try to stay there again if we visit Paris.
