(50737) Köln - 40 Scheibenstraße

Large gravel square in front of the race track. 5 minutes walk to the tram. From there you can get to the cathedral in 25 minutes. Right on the square is a lovely brewery where you can eat excellent food. There is a flea market on the square on Saturday mornings and once a month on Sundays. If you arrive on a Friday, for example, and stand at the edge, that's no problem. I don't know what the situation is like on race day. Lovely place to explore Cologne.
