All the good things other reviewers said applied. I would say 4.8 is a pretty accurate score and well-earned.
The only slight irritations are things beyond Tony's control, but might be worth mentioning:
There is traffic noise, especially if you need the windows open, but significantly dimishes at night. It was not a problem to us and would not stop us staying again.
The regulation self-closing doors need a bit of care to close quietly without disturbing other rooms but manageable.
Kitchen is adequate for a small instant meal - kettle, microwave, fridge, crockery. You will need to go out for a cooked breakfast, but tea coffee, pastry, yoghurt, and fruit are welcome starters.
