@Michelle1476 Be polite, but firm with them, explaining that as much as you'd love to have the time to sit around and chat with them, that you're actually quite busy and that Airbnb protocol is to only text or phone if there is an emergency situation. You should try to keep conversations about things on the Airbnb messaging system, that way if there's contention about anything, there is a clear record for Airbnb to look at. So if someone does call you about some situation, respond through the platform-"Oh, XX, I just read your text message saying that the light in the hallway is burnt out. I'll make sure to get that replaced as soon as I come home from work at 5".
If you haven't already, perhaps suggest places of interest in the area that you think they might be interested in checking out. Maybe even offer to have lunch with them one day-"I'll be free on Saturday afternoon at 2- how about having a late lunch together when I have time to chat." Sounds like they're a bit bored and lonely.
That said, there are situations where I use texting with my guests no problem. I get a lot of single female guests and it's a 20 minute walk to town from my place. I do really appreciate when they shoot me a text saying that they are on their way walking back- it makes them feel safer and if they didn't show up within 20 minutes, I'd go look for them (I raised 3 daughters and like to know that women are safe).
And yes, arriving 2 hours late without notifying you of a delay, and moving blinds around is quite presumptuous.
IMO if you host more than one guest at a time, all guests should be given a set of keys, no charge, with a clearly written agreement that if a set is lost or walked off with, they will be charged $XX for replacement.
