My husband & I went there for 2 days by train from Switzerland (part from our honeymoon).
and I found out 2 days were enough and won't go there again.
We've stayed at Hotel Plaza Athenee, which has a view of the Eiffel Tower. It was lovely & it is the same hotel that Sarah Jessica Parker stayed in in one of "Sex & the city" episodes.

Of course going on top of Eiffel Tower is great. and we went there early in the morning to avoid the long lines.

also:
* Louvre
* Arc de Triomphe
* Versai Palace
* Cathedrale Notre-Dame de Paris
* old down town Paris
* If you have kids 1 day in Disneyland, otherwise I don't recommend it.
* A walk in the Champs-Elysees street. which has number of cafe's & restaurants. make sure to stand in the middle of the street & take picture of the Arc de Triomphe

I always do a research on Yahoo travels. there are lots of useful reviews and recommendations for hotels, things to do & restaurants.
