My check-in time is 3 pm. I am usually done and ready much earlier but I want/need the extra time in case a problem arises (i.e current guest checks out late, there is a broken item that needs to be replaced, my vacuums dies, I'm feeling sluggish, quick repair needs to be done, personal emergency, etc., etc., etc.) My point is, take the extra half hour, you may someday need it.
I usually message the guest when the space is ready and let them know they can check-in early. Many are pleasantly surprised. Many don't show up until well past my check-in time anyway.
