@Natasha372 Just directly quoting the entirety of the review :
Nice and clean place, I would not suggest it for young people or if you are not going to rent a car.
In terms of how/whether to respond, it's completely irrelevant that the guest broke your rules. The place to address that is in your review of the guest.
The audience for your response is people considering booking your place, so it's not the space to air out grievances. You could say something like
We happily welcome guests of all ages who respect our home and honor the House Rules. For those traveling without a car, there is a bus stop 5 minutes away by foot.
If more mature guests are your target market, the first point may be unnecessary. And about the bus stop: this is a point worth making only if there is regular daily service and car-free visitors can easily access goods, services, and activities.
