Sao Paulo is no marked tourist town. Precisely for this reason, a good guide is very useful because we discovered quite a bit of what we would otherwise overlook. Convinced me have the clear city plan and part of the diversity of attractions described. Since I unfortunately was only little time in Sao Paulo available, the advice for 48 hours had a good clue for me.
The guide is in English, but in German, I really can not find anything comparable.
