The location was fabulous and so convenient although the metro station at Place de la Concorde was closed while we were there so we needed to walk to the next station. The ambiance of the boat is very quaint and relaxing. Come prepared for an experience of simplistic, rustic living. Spider webs on the outside of the boat are part of the river lifestyle, so if you are squemish about that, then this may not be the best pick for you, although we did not notice any spiders inside the boat.
We had asked Marco to bring in some additional items during our stay, which he happily agreed to. It was 33-37 degrees celcius during our stay, so we had requested some fans and that seemed to be enough to keep the boat at a comfortable temperature while we were. The boat was anchored in between the dock and another boat, that we could not see over, so we were disaappointed about the lack of a water view. Marco said he swaps location with the outside boat every 6 months, so if having a water view is important, ask first! A unique way to experience Paris, we would highly recommend it for the adventurous traveler.
