No one has ever given us the foul treatment when they meet the husband. He is quite the social guy, but can be intimidating when it comes to putting up with not-so-nice guests. No sarcasm here, just facts and options of staying or leaving.
We have our guesthaus on a quarterly pesticide program. However, guests do open windows and doors and that can lead to bugs getting in. I don't think most would have a problem with a bug unless it was an investation. Best to be proactive and do what you can to prevent them!
