Why does TripAdvisor still show a B & B that closed down in April/May 2016 as the No 1 hotel in Southbroom?
Er ... because no-one reported it as closed? Perhaps you could do it: go to the listing, select to update the details (I can't remember exactly what the wording is), then check "This establishment is closed".
The rankings (#1 in Siuthbroom) are just a blind aggregation of reviewers' rankings - it doesn't imply any monitoring or endorsement by TA.
Thanks Auntiefromjozi - couldn't access the website but eventually posted on their review page. Hope it works.
