Thank you Logan. I've found the entry but cannot access the 1910 Directory to look around as I have other names and addresses to check. I have got as far as http://djvu.sourceforge.net/ but cannot open the contents of the directory.

Does anyone know of a family called Uniatycki who lived in Lwow around 1912 - possibly Grodecka St. Checiow House? and on Listopada Street? or Antonina Uniatycki (Konopska) who died at Checiow House in 1913?
