See, I saw it the other way around: by being clear that it's a house with a crazy layout and it's right on the main road, they will get fewer viewings but they will be people who are already aware of those issues. They didn't try to hide the constant cars going past. It's not for me because I couldn't live on a main road like that, but others will be able to for various reasons. It beats having 50 viewings with 48 of them saying right away, oh no, not on this busy road.
(Others have said that the 'performer' is the agent, not the owner.)
