If you do not know where to stay in Paris, our recommendation is the Hotel Cujas Pantheon, which is very well located in the quatier latin and offers good connections to most places you may come from or go to (see this map and more details). Make your reservation as soon as possible, since you are likely to find the hotel full it your just show up at the desk. Better call than send email, so that you will know right away whether they have rooms available.
(We used to recommend the Hotel Central des Ecoles in the same location. However, after standing went really down, this Hotel has been renovated, is now called Hotel central Saint Germain, and unfortunately prices are now much much higher.)

From hotel Cujas, the simplest is perhaps to
take RER C form Saint-Michel to Versailles-Rive-Gauche and
Versailles-INRIA shuttle there (or the city phebus, line B
[click on Ligne B.pdf] between Versailles and INRIA.
A little faster but less flexible in the schedule is to take RER B to
Chatelet, change to RER A (direction Saint Germain), exit at Place de
l'Étoile, and take the Paris-INRIA
shuttle.
