Agree with the others! As hosts, we should do our best to be gracious, but when people become abusive and demanding, it's important to be clear on our boundaries. It's a delicate balance between extending yourself in ways that make someone feel welcome without signalling that you're a doormat. Once you know someone is a vulture, don't give them another inch.
Asking for extra photos is a red flag for many hosts. You have a lovely set of pictures that show every element of your house. There's no need to ask for more.
Same with requesting transportation - they've hired your living space, not these other services. It's fine for them to ask and fine for you to decline.
If you get these clues before you've accepted, just decline them. If they become demanding after reserving, be clear about what you can offer. "This place is meant for self-sufficient travelers. I'm happy to give you some info about the accomodations, but won't be available to you 24/7. If you don't feel this is a good fit, you can cancel through the Airbnb system and I'll send through a refund" (be clear that THEY need to do the cancellation - you don't want to be penalized)
I get the same issue with taxes paid in person. Occasionally people balk, even though it's stated in my listing (as I see it is in yours). It's helped that I send an e-mail the week of their stay with check-in instructions and the amount to be paid (cash!) when I meet them. If they're still acting weird about it, this would be a spot to get Airbnb involved.
Most of the other during-stay issues fall along the same lines "Thanks for your (12:30am!?) message - the glasses are in the cupboard. Unless it's an emergency, I'm unable to answer messages between 8pm and 8am." If they continue, it would be good to involve Airbnb to re-house them.
On the check-out time...this is a big peeve of mine. We're not hotels that can put the next guests in another room, so it's important people check out on time. I give people about 30 minutes after check-out before I start opening doors and moving in with cleaning supplies. I can even manage to do so while keeping up friendly banter about how their stay was and how I wish I could let them stay longer, but expect the next guests in 3 hours. If they're there past checkout, call Airbnb. You may be able to charge them for an additional night.
Threatening to leave a bad review if you don't XYZ is extortion. If they're daft enough to do so over the messaging system you can flag it to Airbnb.
As for what to do now? I'd hold off on reviewing the guest until the very last moment. If you're lucky they won't leave a review. If they do, it's still in your best interest to hold off. Their review won't appear on your page until you've both reviewed or the two week review window is up. Hopefully you can get a more recent guest's (good) review to appear before the bad review. And be honest in your review of them. There was a recent thread (in Hosts?) about some good verbiage to use for bad guests.
Even if they do leave you a bad review, don't sweat it too much. It happens sometimes. You can leave a response that's professional and makes clear that they were difficult guests; it's easy for potential guests to see who the problem was.
