Hi @Allison13,
Yes Alison the previous responses are excellent.
There is another option as well.
It may be that there are specific issues such as access, stairs or something particular that the potential guest is concerned about.
Maybe they had a poor experience somewhere else, or a simple matter that needs clarity. Guests are paying in advance- sight unseen, it's natural some people are apprehensive. There is a lot of variation in hosts and venues and some bad publicity out there, as well as the good, so naturally a small few guests will have concerns.
Just write back and ask if there are particular matters which the guest is curious about and you may find that a couple of emails sort out any mutual concerns.
It's about helping guests and host make choices that match their needs and expectations.
Sincere Regards, Christine.
