This is an outstanding location and staying on a houseboat on the Seine was a unique experience. I had never been to Paris (or Europe for that matter) and I am in my late 60's. I was a little apprehensive about safety and language issues, but I was totally comfortable right from the start. The only warning, and others have said this, is that the bathtub is challenging. It is a small space and you need to climb up a two step ladder to get in. The trickier part is climbing down when you are wet. There is also a ladder to get in and out of the apartment, but not a big deal. The communication with the hosts was perfect.
