I agree with jno.
Pillows? Do what Premier Inn does – provide one on the bed and another (of different plumpness) elsewhere in the room. A note on the bed tells you what they have done. Different people like different pillows and all hotels should cater for that. No matter how much or how little you’ve paid, if you book a room for two then two glasses should be provided. You should not be expected to share a bathroom glass. These are things that should be checked as the room is turned round and guests should not have to spend their time asking for things that should be provided as a matter of course. My biggest gripe is light bulbs. It is something to remark on when you have a room in a hotel where all the light bulbs work. You see “twin” lights where only one works, chandeliers with a bulb or two out. Bathroom mirror and bedside lights are particularly prone to being inoperative. Once again, these should be checked by the person cleaning or changing the room. Something that cannot be cured immediately uis poor room layout. Many hotel rooms appear to have simply had their furniture and equipment thrown in with no thought. Dressing tables where the nearest electrical socket is ten feet away; mirrors sited whrere they cannot be properly used; wardrobes where you can only open the doors if you move the bed two feet to the left.
Hotels lay themselves open to poor reviews if they let their guests down with these minor shortcomings. It costs virtually nothing to put many of them right and they should be on the ball.
