Marc is an incredibly gracious host and a great person to know while in Paris. His english was excellent so communicating any questions to him or getting his insights into Paris' best kept secrets was easy. Marc was very timely in always answering any question I had prior to arrival as well as when I was in the city. What can I say about this boat? Location, Location, Location. There is no better place in all of Paris to stay then on the Seine. You are literally in the epicenter of Paris with all major attractions and neighborhoods within walking distance. Quiet neighborhood cafes and groceries that are off the tourist path are very close as well. I can honestly say that this boat was one of the main reasons why my trip to Paris will go down as one of the better weeks I have ever had. That said, please acknowledge the fact you are staying on a boat. Boats move, all the time. Boats have their own quirks and characteristics and this boat is no different. Be at ease with that and accept it as part of your experience and you will have an equally gratifying experience. I cannot recommend Marc's houseboat enough.
