I get a lot of booking inquiries and requests at all hours of the night. It amazes me that folks are up, and placing requests at 1am !
Although I keep my phone next to me, it blocks certain incoming messages between 10pm and 6am.
I leave a notice for guests that I am available to respond to requests between 7am and 9pm, except in case of emergency.
For someone checking in after I have gone to bed, I tell them to call me if they have any issues checking in.
My last miserable review came from someone who sent me a sarky message regarding an issue with the TV, at 7.30pm on a Sunday night, the last night of a 5-day stay, while I was out at dinner. The only communication from her during the entire stay. I did my best to respond to her via messaging, but couldn't rush back to help at that moment. 3 stars for that. Clearly, she'd been having personal issues throughout the trip based on the review (weather was one - it rained a lot that week, and lack of a coffee maker and toaster was another, although my listing does not indicate a kitchen is available). But, of course, the host is responsible for the entire experience. 😞
She did not ask for any refund, and I did not offer any.
