There are additional quests for the Tea House, like there was for the Witch's Abode. If you don't get them after completing the main quests then clear additional collection item quests through to combining the collection you may already have.

I don't know how many more there are, just got the first one. But it will give you something to do in the location besides just collecting keys.
