Hi-thanks for the info. Curious about what you thought of the hotel? Did you eat breakfast there?

Take the 4-star rating with a grain of salt; the lobby/reception area is lovely as are the bathrooms, the bedrooms are another story. It's more of a 2 1/2 to 3-star hotel.
Try to avoid the 11th and 16th floor rooms; actually, if you receive a room you don't like do NOT hesitate to request another. Even though you bid thru Priceline don't accept a bad room (see link below for "reviews" and helpful info) - be POLITE but FIRM.
Appearantly there is some street construction going on in the area between the Balard station and the Sofitel.

Read this thread for further info:

As for breakfast, I would take the Line 8 to the Ecole-Militaire station and walk a block or so to rue Cler and either pick up breakfast in a patissarie or boulangerie or have it in a cafe there (will be less expensive and tastier).
My favorite boulangerie in rue Cler is about a block or less away from the Jeff de Bruges chocholatier. It's across the street from a "deli" (where they have really good picnic food) and has the best baguettes that you can purchase as half loaves and good quiches (sold in front of the boulangerie entrance).
Alternately, you could take the Metro further into central Paris and have breakfast there, I just suggest not eating at the hotel unless it's included in with your stay.

If you need more info or suggestions, PM me; however, I am off for Florence soon so may not be able to respond during mid to late January.

At the Sofitel, ask for a room with a Sofitel My Bed as those rooms have been recently renovated and the bed is very comfortable.

I found a room in Sofitel Forum Rive Gauche on their website for 128 euro(prepaid rate without breakfast). I wonder what I should expect.

Is there any decent cafe/restaurant nearby where I can have breakfast and dinner?

Sorry to bring up this question again...

Making a trip to Paris this weekend (arriving Friday ca. 1800 at CDG).
Staying at the Holiday Inn - Paris Montparnasse (10 Rue Gager-Gabillot Paris 75015). According to mappy.com it is only a 20 minute walk from the Gare Montparnasse where the Air France bus stops (can also take the metro from there of course).

The other option is the RER to Chatelet-Les Halles then a couple of metros (4 & 12) to Volontaires.

I'm leaning towards the bus at the moment, but will that be a lot slower than the other option that time of day?

All suggestions welcome.

Merci!

The bus ride should take about one hour- it makes a stop at Gare de Lyon on the way.

Are you arriving at terminal 1 or terminal 2?

According to the RATP itinerary planner, RER B to Chatelet, line 4 to Montparnasse, and line 12 to Volontaires will take about 50 minutes (though changing lines in those large stations will definitely take longer than the 3 and 1 minutes it quoted, so I would say a minimum of an hour).

It also proposes Bus 350 to Porte de la Chapelle metro, then line 12 to Volontaires. Estimated trip time: 1 hour 10 minutes.

Another option: Roissybus to Opera, then Bus 95 from Auber to Procession (essentially just around the corner from your hotel). This looks like it takes about 1 hour 45 minutes, though.

Air France bus to Montparnasse, then Bus 95 from Montparnasse to Procession (AF bus transit time plus 12 minutes for Bus 95).

Also RER B to Luxembourg, then Bus 89 from Luxembourg to Alleray (also just around the corner from your hotel). 1 hour 6 minutes.

I probably haven't covered all of the options, but there are more than I would have imagined!

I know you weren't asking me, but I stayed there a couple weeks ago. The breakfast, while providing a good view, is not worth the 25 euros it cost. The gym and pool are both nice enough and definately provide the best workout view I've ever had.
