Note: I booked Guillaume's Marais flat for family, so am reporting their experience secondhand. First off, his responsiveness and communication was outstanding - a big departure from many big city hosts. Second, the flat was accurately described; in fact, we would say it was slightly undersold: the location is exceptional and central, separate spaces and doors make it live larger than a traditional 1-bedroom, and it was clean and secure. Guillaume's professionalism enabled our geographically dispersed family to have a wonderful post-pandemic reunion. We wouldn't hesitate to stay in the Marais with him again. Thank you!
