Most disappointing was Rubens at the Palace, 5 star hotel and the view some some loudly humming ventilation unit on a roof. One of the most expensive hotels I've stayed in and I think only one of two/three occasions I've requested to have my room changed, couldn't believe how poor it was.
Had plenty of standard travelodge views of car parks / A-roads, and cheap London rooms looking out at a wall, sometimes in the basement. None of them particularly memorable, I couldn't tell you which hotels had these crap views.
On a related note, there was a hotel in Canary Wharf (Brit International) that I used to stay in, I'd always book a room with "no window" if available as it was cheaper and then when I'd check in there would be this charade where the person on the desk would ask if I'd like to upgrade to a room with a window. I'd politely decline, and then find my room had a window anyway, not the worst views by a long shot with the water and lights from sky scrapers etc. Pretty sure it was just a way of selling rooms off cheap without undermining their brand / having to advertise all the rooms of that size at that price.
