I've just booked a vacation rental for 4 nights in the Loire Valley. The rental is a private cottage owned by a couple that live in the main house on property. The rental cost includes all necessities such as utilities, linens, toiletries, and cleaning services. Is it also proper to tip the owner?
I don't want to offend them by offering a tip if that is not appropriate, but want to plan accordingly if a tip is acceptable/expected/recommended in this situation. Any help is greatly appreciated!
