REEFLEX Résidence Internationale
inside the Campus, close to
the Math. Dept., it is studio style with small kitchen corner. Does not offer breakfast.
Under special deal with the University,
for booking, it is necessary to contact M. Tibar. It may run out of space in certain periods like month of June.
Other lodging: there are some more hotels close to the campus, or downtown Lille and then one has to travel by metro (about 15 min away from central Lille).
I’d suggest to use booking.com for finding something suitable.
Metro:
map . From the railwaystation Lille-Flandres, take Line 1 (the yellow line on the map) until station "Cité Scientifique-Pr Gabillard",
then 3 min walk to the Reeflex hotel,
and 5 min walk to the Math Department.
From Lille-Europe, take the Line 2 (red line) to Lille-Flandres (first stop), then change the platform for Line 1 direction
"Cité Scientifique-Pr Gabillard"
Tickets: vending machines. (Same ticket is valid if you change metro to bus or conversely.)
The conference will take place on the campus Cité Scientifique, in the building M2 (map
of the campus) "Salle des Réunions" , ground level +1.
Campus facilities. There are no shops inside the campus, but there are several cafeterias where one can buy breakfast
or lunch by credit cards only (no cash!). One can find coffee, water and cookies inside the Math Dept, building M2 ground level
(vending machines; coffee is cheaper since subsidised).
For dinner (and other shoppings) one can use the mall called ‘V2’ at 10 min walking distance from the hotel Reeflex.
