I stayed in a Premier Inn a couple of weeks ago. Room very clean. Tea and coffee making still available in the room.
They will only clean the room every 3 days of your stay. But it does get cleaned between each new guest.
No buffet service, all sit down for breakfast. You get the option of full breakfast or continental. I chose continental as I don't each much at breakfast. Slightly disappointed that you only have options now of either crossients, toast or something else [ can't remember off hand ]. You can't have all three. So two slices of toast, butter and jam and a coffee was £6.99 which is a rip off! For a buffet breafast you used to get the choice of crossients, toast, muffins, cereal etc, and allowed to pick and choose how much you wanted.
You could get a drink in the evening at the bar, but again seated service only.
You are meant to wear masks in indoor spaces, but very few guests were doing this. Hand sanitiser was available at reception. It all felt okay and safe to me and I would do it again, but give the breakfast a miss!
