Amazing Valet & Waitstaff, Subpar Conceirge
My husband and I stayed here for an entire week (7 full nights) so we had plenty of time to experience all that the hotel had to offer. I'm going to break this down my section and explain our feelings on each one, some great great and would get a 5 star rating and others were poor.
Valet - these guys/gals were the highlight of the stay. I have never seen such responsive, friendly, attentive, knowledgable valets. Even when it was busy we never waited more than a few minutes for our car. When we needed a cab they were on top of it, when our friends wanted to stow their bikes they were on top of it, etc etc...you get the picure.
Breakfast Buffet - sadly this was a let down...everyone on this site raved about it and I thought it was very average. I expected a little more from the top rated Denver hotel and an Embassy... Don't get me wrong, you'll have a filling breakfast was just a little boring and plain.
Breakfast Waitstaff - AMAZING! They were so efficient and friendly. JRand was our favorite! 
Rooms/Housecleaning - the rooms were your standard suites, very nice and well cared for by the staff. Our room could have used a one over with the vacuum but otherwise we were pleased.
Conceirge - this is sadly why the review is only getting an average rating. RUDE RUDE RUDE. We arrived early on a Sunday morning and my husband had called ahead earlier in the week to ensure we could have an early check in (unknown to me we 100% had a room available because there was a surprise basket of goodies he had arranged for me, nice hubby!) Anyway...regardless of that the woman at the Hilton Honors counter didn't even look up to greet us, stared at me until I explained we were checking in, then gave us attitude because we were so early and she didn't think she'd have a room available. I understand that she would not know about our special situation until looking up our reservation but her whole attitude was inappropriate and certianly no where near Hilton standards. In addition any time we went back to the service desk throughout the week we were greeted with grimaces and sub par service not indiciative of a Hilton property. 
Sad to say this ruined the experience though we did have some wonderful highlights. I would not stay at this location in the future.
