I just stayed at the W Hotel Paris for 5 nights. I booked the Cozy room for €259 at prepaid Hot rate. As the stay got closer, cozy rooms were sold out and the same €259 Hot rate became the next category up. Then the hotel became completely sold out couple days before I arrived.

I was upgraded to a Marvelous Suite which was very nice. I was glad not to have to experience the Cozy room. Since ant_west has described most of the room types in detail, I'll just add that the 4 oz size bathroom amenities are very nice, especially for a 5 night stay.

The Plat breakfast amenity was the full buffet, no mention of any continental breakfast. I sign for the €38 check each morning, add tip , and then the €38 breakfast never shows up when I checked out, only the tips. The selection was not very extensive but more than adequate for what I needed, especially after big dinners the night before. I think this is the first time I have ever had strawberry juice at breakfast. I was hoping for Iberico charcuterie from earlier post, but no such luck. The cheese selection was good the first 3 days especially the chevre, then the last 2 days there was no chevre.

The staff was all young, friendly and very helpful. Best staff of any hotel in Paris I have stayed in.

Overall I was very glad I found the Hot rate and be able to experience W Paris, otherwise I wouldn't be able to stay here based on our corporate guidelines.

Diagonally across l'Opera is RoissyBus stop, nonstop to CDG at €10.50 per person. The bus runs every 15 minutes. A very good travel option, much easier than RER and a lot cheaper than taxi.

Printemps down the street has a LaDuree stand, so does CDG, in case anyone is looking great macraons.
