Excellent time. Highly recommended.
We hired a narrowboat from Minervois Cruisers at La Someil - very good service. Boat was in good repair (those from some other companies did not seem so good).
We hired bikes, which was a real advantage as it allowed us to explore around the canal (as well as get fresh bread in the morning!).
Take gardening gloves and old clothes to handle the ropes - the toilets on all the boats empty straight into the canal, there was no smell but the thought made us rather obsessive at hand washing.
If you are getting a bigger boat make sure that it has bow thrusters (wasn't relevant for the narrow boats, but we saw some people struggling).
Last top tip - don't plan to go too far. It is much better just to chug along and tie up away from the villages (you can tie up anywhere on the canal - use the tree roots as secure anchoring points).
