If sleeping doesn't work you could try Unrelenting Force to wake her up or leaving the inn for ten days so it resets, there are some commands mentioned in the Nexus forum to fix this -

Setstage MQ105Ustengrave 20

Setstage MQ106 5

The two are needed as the two quests there was no reply in the forum if it works or not though.
