Oh, that's too bad you didn't get to meet her and get it over with for all that nervous anticipation! But you got a little practice and have an idea how it will feel, etc. and she made a mistake (instead of you :-) so that's comforting. It's nice to know what lengths she'll go to (the 20 minute wait outside an empty flat trying to get someone to answer the door :-) to help too. You'll be a piece of cake to her to befriend compared to the empty flat
