I use airbnb quite a bit and usually check in time isn't a huge concern, but sometimes a few hours can make a big difference on where I want to stay if I'm coming in via plane or train. If a train gets to the city at 11am and I have luggage, I'd much rather have a noon check in then a 1600 check in, for example. Am I missing the filter option for check in times or does that not exist?
