How to get there: by train from Plaça Catalunya with the Generalitat Railways (FGC) line Barcelona-Sabadell S2, get off at Volpelleres station, the next one after Sant Cugat station. From there it is a 5-minute walk. I have attached a map in the next message indicating the walking route to the location in red color. I also send train schedules departing from Plaça Catalunya (arrival at 8pm) and last departure from Volpelleres at 1:42am at night. The party ends at 3am. There are taxis for those who resist until the end of the party to return to Barcelona around that time.
