Hi @Rick4734 ,
It's clear from your message that you've done everything in your power to rectify the situation and make it right for your guest. Offering a refund, free snacks, and a sincere apology shows your dedication to customer service and your genuine concern for your guests' experience. You've demonstrated professionalism and compassion in your response, and I'm sure that your guest will appreciate your sincere attempt to amend the issue.
I know it's unsettling to think about the possibility of receiving a poor review despite your efforts to resolve the issue. We are not big hotel chains; we are individuals trying to do our best, and mistakes happen. As much as I try to avoid it, I am sure it will happen to me one day too! What's most important is how you've handled it, and you are actually an example of good hosting behavior.
Please try not to be too hard on yourself.
