Oh and one more thing: I find the Hyatt and other major Paris hotels to be less charming than the smaller boutique hotels and apartment rentals. On our first trip there, we stayed at the Relais Bosquet in the 7th, and loved it, but their prices have increased a lot since our stay. You might also look at VRBO for apartments, but makes sure the apt has more than a handful of reviews. Anyway, the major chain hotels just seem a little cold to me.
