Before you read this, you may want to know thatthere is nothing interesting in the house, but you can get a lava cookie from her (a white Flute in Platinum). The lava cookie only revives a little health and can be used only once, and the white flute only attracts Pokemon which you can do if you have a Pokemon that knows Sweet Scent.
The lady in front of the house lost her key card, as you already know if you talked to her. Go over to the building that you go to to rest your Pokemon (the check in building for the hotel area), but don't go in it. Use your item location thingy on the Poketch by tapping it, and a dot should appear. Go right next to the dot and press the A button to pick up the key card. Go to the house and talk to the woman again. She will go inside. Follow her and talk to her to get the lava cookie/white flute.
