Questão jurídica principal
Whether the cantonal court arbitrarily counted the apartment as having five rooms rather than six for statistical rent comparison
Decisão extraída
No arbitrariness was shown; the lower courts could exclude the dining room and rely on the five-room statistical category.
Fundamentação extraída
The appellant failed to demonstrate that the room-count criteria used by the courts clearly diverged from those underlying the cantonal statistics. The contractual and move-in documents did not compel a contrary finding.
