Tips for good hybrid fit

I will be in France next month and plan to rent a bike for a few days of
touring. It looks as though the best I can hope to find are some hybrid
bikes (fattish tires, upright handlebar, etc.) Bringin my bike just isn't an
option this time.

What should I watch for to get a good fit?

I have never had a good experience renting hybrids, but it occurs to me that
may have been because of other issues such as poor fit. I ride a 25"-frame
road bike that well-meaning bike-shop personnel frequently tell me is too
big for me (based on my height, just under 6 feet).

They couldn't be more wrong, but I think there must be something
counterintuitive about how I am built, and perhaps this has translated into
a bad fit when renting.

With any luck the French bike store I get my rental from will fit me well.
But what should I look to make sure they do? Other questions:

Would my touring saddle work well on a hybrid? It would be easy to bring.

Does a 25" touring-bike frame "translate" into any particular size hybrid?

Thanks for any help--please reply to the newsgroup.

I understand that this shop in France rents bikes that are more
comfortable and faster than hybrids: http://www.airodin.com/.
