Edinburgh’s Holyrood Hotel joins Marriott after £10 million refurb – Business Traveller
"The former Holyrood Hotel in Edinburgh’s old town has been reflagged as the Edinburgh Marriott Hotel Holyrood following a £10 million refurbishment programme.

Situated opposite the Scottish Parliament building, Dynamic Earth science attraction and Royal Holyroodhouse, the 160-room property now features the brand’s signature M Club Lounge for Marriott Bonvoy elite members"


Note that, in it's wisdom, Marriott has included all the previous reviews for the hotel in its previous incarnation in the "Reviews" section on the official webpage. So we can see, for example, "Shabby and run down. Very grotty and run down hotel."
