The note seems to be placed pretty far from where it seems like the building(s?) is (are?) - apparently they are the two to the south, where the top one currently has the address 2220 E M Franklin Avenue. One seems to be the "A" building, and one seems to be the "B" building. It's not clear where the classes, specifically, are offered.

What's more confusing, the location here seems to offer more than just the classes. They also do blood donations and perhaps some other admin tasks. So I'm not sure 1) how to properly tag the buildings, both address-wise and name-wise, and 2) whether or not the website given, which goes straight to the "take a class" option, should be used for the buildings as a whole. Or whether that information belongs on OSM in the first place (as opposed to the generic "American Red Cross" preset). 

Finally, to really throw a wrench in things, when I searched, I found a news blurb from not even 24 hours ago about how the area will be under construction soon!
