We need help with our vacation plans

My two or three friends and I want to vacation in Paris with my one year old daughter for about 4 to 6 days.

I desperately need help- I can't figure out the regions and I prefer to stay in an apartment rather than a hotel- my daughter is very well behaved and so are my freinds and I

We want to do the museums, eiffel tower and the like- typical tourist attractions.

We want to travel around the ending of august- beginning of sept 2009.

Any help will be greatly appreciated- like any leads on apartments, best regions to be in, which airport is best to land in- etc

Thank You
