The Summer School will take place:
from Monday July 15 to Thursday July 18 in Vilanova i la Geltru, 40km south Barcelona, at the Universitat Politecnica de Catalunya campus. (www.epsevg.upc.edu)
Friday July 19 in Barcelona at the site of the TC-4 Symposium as parallel event.
Vilanova is not a big city, and there is not to much offer for accommodation. Prices are lower than in Barcelona, for sure.
About special prices, we are renting a beautiful house only for the students.
