Myself, family and friend had the pleasure of staying at Jean-Jacques' stunning house boat for a week in July and I couldn't recommend it highly enough!
I honestly can't think of any negatives, the accommodation is excellent and the view second to none. To be able to spend the week in such a unique setting helped make it a holiday never to be forgotten. It's very well located, only a 20 minute stroll down the river to the Eiffel Tour and there is plenty of public transport on the doorstep. It has all the amenities on board that you will need. And a very good sound system!
If I find myself in Paris again I would not hesitate to stay again.
Merci Jean Jacques pour nous permettre de rester, C'etait tres beau!
