I've checked on GMaps and saw that's Zārāndoā Kalea, number 10. That's what the number 10 means, right? And the other note should note Zārāndoā Kalea, 13?

If that's so then we could even map the street's or neighborhood's name, but I'm not  sure if it's Zārāndoā Kalea or Barrio San Isidro. Do you have any pointers on this?
