I dont think the name tag for this building "Keep Out" way/500793152 is a appropriate name tag for it... suggest updating the tags here... there are other suspect name tags in this area as well

unclear if SFI hostel or Olympic hotels are both here or just one of them, should be updated to reflect which one is really in this building

unclear where this poi is located: node/5322910424 its not at this location from what I can tell. Perhaps its actually located somewhere nearby?

water polygon for this drain should be updated to represent the culverts underneath it, suggest either making separate water polygons for each area outside the culverts

unclear if this is real or just spam... anyone who knows, perhaps should be removed if its spam?

building outline should also encompass the building parts in the center here. Its also required for proper 3D display.

all these trees here are incorrectly tagged, they should not have the name as the species type instead they should follow the osm tree schema: natural=tree
