XMM-SSC, Consortium Meeting #31
CEA Saclay, April 16-17, 2018
The two main options are near Saclay or in the south of Paris.
Have a look at the transportation page to weigh the pros and cons.
The choice of hotels within walking distance of one of the two buses which run to Saclay is not enormous. I give their direct web sites here (no particular preference order), but they are often in French. They are also accessible (in English) via Booking.com.
- ApartHotel Adagio Massy
- ResidHome Massy
- Sejours et Affaires Massy
The night life is rather poor there, but for a short stay it may not be a problem. The last two above are in not particularly pleasant surroundings (a business quarter).
There are plenty of hotels near the RER B line (Denfert-Rochereau, Luxembourg, Saint-Michel). See here a Paris metro map.
Another possibility is near porte d Orleans, coupled with using the chartered bus from porte d Orleans (see How to reach the meeting spot) or RER Cite Universitaire. Hotels are cheaper there, but it is further from Paris center.
