One night stay. Diamond member, with same day booking.
Letter from manager, with introduction and advised of robes, slippers, water and a gift, but sadly none. Not fussed, as only a night.
Was given a complimentary drinks voucher, along with breakfast voucher. Nice enough breakfast, and fried egg made on request.

Room was clean, bed comfy. Nothing startlingly bad, nor amazingly good - just a solid one night stay.

With the Metro being off on the airport branch this week, if I'd have known, I'd probably have just stayed in the Hampton opposite the station.
