Are reviews seen by HO before being posted?

Wow. Mind boggles.
Reviews are blind - neither person sees review until both have posted or until 14 days passed.
Reviews are optional - while leaving a review helps both parties then there is no obligation.
As @Silversitters noted, this appears more like employment than housesitting. Should you deem that incremental animals was an issue (i.e. inaccurate listing) then raise a member dispute. We’d have left much lower than 4* for accuracy of listing if arrived onsite and found this surprise.
