Hotel: Clean and neat.
Staff: Friendly and helpful, for example, offering assistance on how to find our misplaced baggage (lost, and later found, during our commute into London), and providing cutlery for eating our meal delivery in our room.
Breakfast: Wonderful! Best I've had in a while. Buffet with selection of cereals, cold meats, traditional English breakfast, scrambled eggs 😋, breads, and fruits and yoghurt.
Note: In the quiet of the bedroom you can feel and hear the rumble of the underground. Noticeable, but not enough to bother me, my wife, or 1.5-year-old.
