Question juridique clé
Whether the apartment's rental use made reception non-private and subject to commercial/generic fees.
Solution extraite
Reception in the rented holiday apartment was not private during the rental periods; fees were owed pro rata for those periods.
Motifs extraits
Private reception covers only the declarant, persons living in the same household, and free guests. Paying tenants are not guests, and an adult son renting the apartment is not part of the same household. Thus rental periods fall under commercial or gewerblicher reception, with no material difference in the fee level.
