text: These look perfectly sensibly mapped to me. The flats (immediately to left of marker) are Pemberton Court which is in the addr:housename & the flat numbers in addr:housenumber (although local to me I think we'd use addr:flats, this is not a firm convention). The street name is Pemberton Avenue, so individual addresses would read Flat 1, Pemberton Court, Pemberton Avenue. 
  
  Generally in a case like this I think rather than adding a note you might get more precise feedback my asking on the changeset in which these data were contributed. The original mapper will have far more direct knowledge.
  
  For instance addresses of flats 5-8 appear twice which may be an error.
