Another easy week, map 7
is up. Fwiw, the same car (903) was used each time (and they didn't bother to wash the graffitti); also, it must have been filmed quite late, according to this site
the last trains don't clear the station until 10:30-11:00 p.m.
Addition: I assumed they started the Mendoza task from their hotel, which is why I shouldn't assume things. The actual starting point was the courtyard of the tapaseria "El 23" on Calle Chile, which matches the graphic the show put up.
