We pass our condolences to both you and your family, as we did when we were told of your father's passing by the primary contact for your family. However, I would contest your comments. Firstly, we are not in a position to only show 'positive feedback' on this site, or any other. Reviews are rejected only when they are proved to be non-compliant with their review policy. The decision to show reviews is not in our gift.
To put your mind at rest I would suggest that you request to see the communication between the home manager, the staff team and the person in your family who was the primary contact with the home. You will also see the respect the home had for your father and how they cared for him.
With regard to the lack of face masks worn by staff, I would comment that this would be highly unusual and should you wish to take issue with this please feel free to write to the home manager with full details, so that the Complaints process can be instigated.
