@Mike-And-Jane0 could well be correct. The location shown on the listing is approximate and can be quite broad. You cannot show the exact location prior to booking for security reasons, as I am sure you can appreciate. However, once you have booked, you will be supplied with the exact address, which you can look up and cancel within the 48 hours penalty free if you're not happy with it.
If you feel that there was something very misleading other than that, i.e. the location is way outside of the area specified in the wording of the listing (e.g. I have seen listings advertised as Central London when they are actually in Zone 3, have no underground station and are a 45 minute overground journey into Central London), the address given on the booking is not the address where you are staying, that sort of thing.
If the listing is on the very edge of the red circle, well that's not really the host's fault at all because it's the Airbnb system that generates the maps and circles. The host has no control over it at all. It is still not great that the host has still not responded to you in five days, and your booking is so far out that I wouldn't mind if you cancelled, but bear in mind, if they have done nothing wrong (i.e. it was the Airbnb generated map that confused you) and you are expecting them to cancel, they will most likely not want to do it. Hosts face a load of penalties for cancelling guests. They can still agree to issue you some kind of refund, e.g. if the dates get rebooked, but that is at the host's discretion and they can't refund you the Airbnb fees as that is out of their control.
