The Raijin stable is on tour in Osaka. They don't stay in a hotel but in a temple. Not to mention temples have cemeteries. Tanaka is scared of ghosts so he can't stand it. Takinokawa-zeki sends him on an errand, so he's glad to get out.
They're letting me stay for free, 
so it's the least I can do.
Ich darf hier gratis bleiben,
das ist doch das Mindeste.
Me dejan quedarme gratis. 
Es lo menos que puedo hacer.

Estou dormindo de graça! É 
o mínimo que posso fazer!
