Room was like having an airport runway next to your bed the noise!!Do yourself a favour stay away save ur £
We arrived after a long flight check in was quick and easy no complaints.
We were given a room on the left of reception on a high floor. 
Once in the room was very noisy and ready for bed we realised that the noise of what must be a v loud generator or maint unit was going to continue indefinitely and we were not going to get any sleep. 
I phoned to reception to change rooms we were actually offered the room directly below!!! I said how is that going to help with the noise issue is there anything on another side? I mean was he joking! 
He replied that they had nothing else to offer us and we would have to downgrade to a small queen room on the other side.
I asked him to confirm this as we had paid for a large executive room.
I was told there was nothing else he could do so basically like it or lump it!
Felt we had no choice but to move to the downgrade if we were going to get a wink of sleep.
So transferred the room smelt old and musty and was so small.
bed was comfortable I will be fair in the review and we did sleep well.just the guest experience as a whole in terms of everything else was rubbish.
Bathrooms were pokey and needing a refurb.
In fact whole hotel needs doing up.
Breakfast was disgusting: fact No choice and cold stale vile food. The choice was cold dry scrambled eggs with nothing to go with a cooked breakfast. Some ropey sausage no bacon or anything else.
Couldn't eat it and had to go to Walmart to buy food across the road.
Was planning on staying again on way back from Rockies but glad didn't prebook. We chose the doubletree Hilton Denver Which was a pleasure to stay at and a much better choice for similar cost.
I would never stay here again and as an ambassador member of the intercontinental group it was a real let down as i normally choose a hotel within this group and had to choose a diff brand of hotel it was that bad and will be writing to let them know.
Hilton seems like they offer so much more value and a better honours programme which guarantee benefits.
