so sorry i missed this Kaz!
Glad to hear your Aunt is doing well, fingers crossed she is mobile and can get home soon, tbh you are safer recovering at home in regards to the normal infection risk and more so at this time of year with norovirus etc, so deffo best to be home!! If she has all the aids I am sure she will do well!
We have rehab up here, my 1st placement was in an ortho rehab ward so we had many ladies who had similar ops come to us for a few weeks before going home (ended up there for more than a few though!), but tbh if your aunt can mobilise and manage independently I would say home is best!
