Hey y'all, I'll be heading to Europe for a bit this summer and wanted to do some BJJ while there. Destinations listed in the subject line; any recommendations? Won't have a car for any of the trip, so public transport will be my main way around. I'll be staying in Prenzlauer Berg in Berlin. Close to the city center in Barca. Close to the main train station in Prague. Near the coast in Marseille (?). And one other TBD city. Thanks.
