When I asked the host questions through Airbnb, she'd answer complete emails with only e.g. a "yes" and a couple of times she wouldn't respond at all so I had to re-send my questions. I wasn't comfortable with the unresponsiveness and the lack of care with answering messages fully because it made me think that she might back out of the booking last minute. I hadn't even received a response from her about how to check-in when I boarded the plane to New York. It was important for me to know these details because I was going to arrive very late (11pm) and didn't want to be left without housing or without someone there to let me in in the middle of the night. I did eventually get a response from her which I received after my flight - however, if I wouldn't have had access to wifi or no connection on my phone (which is very likely when travelling to a new country where you don't have a local sim card), I wouldn't have seen it.
