A Complete Disappointment
I stayed at the Dana in May of 2011 hosting both a party and staying in one of their king suites. The club, the hotel and the experience was amazing. Being a sales professional I hold customer service in the highest regard, so as a good customer I booked a one night stay at the Dana because I was attending a wedding downtown. What ensued could have been one of my worst experiences at any luxury hotel I have ever stayed at.
Just to give some background, I have stayed at hotels all over the world and find the W to be the best luxury hotel brand with the best service and most cleanly. The first time I had stayed at the Dana I had actually booked the party and stay through a concierge that has never made a mistake in my opinion. For my most recent stay, I decided that I would make my own reservation because sometimes I wonder if the restaurants or hotels my concierge recommends put on an act or if they are truly customer oriented. 
Let's begin, we arrive early afternoon on Saturday and valet the car so we could quickly change and head out to the church. We head up to check in and are greeted by a plump, rude man at the front desk who basically felt like smiling and being courteous had gone out of style like the 5 o'clock shadow and hangover look he was sporting. We then got on one of the dirtiest elevators I have seen which looked like the hardwood floor had not seen a mop or refinishing since the hotel's inception. Walking down the common corridor there were marks all over the walls and a smell that I could compare to my days of playing baseball on the road and staying at the Holiday Inn in the Quad Cities. 
All bad things aside, the room and view was beautiful so I can't fault the Dana for that.
Story continues...we get changed quickly go down to get our $44/overnight in/out valet car and figure we will make the wedding just on time. Only problem was the car took 25 minutes to get and of course made us late for the ceremony. 
Just as an aside, there was no apology, the valet service was awful and the front door guy lied on where the car was. I understand that not everything would be perfect, but there was just a lack of skill and tact that the whole staff from the front desk to the valet the staff at the Dana was lacking. What is funny I usually will tip even on bad service, but I made it a point that I would not tip for any part of that valet service as I felt they owed me money for even thinking they were competent enough to drive my car. 
To conclude, the Dana does have some of the nicer rooms in the city, but this is a place that exudes the "new money"/uncultured feel, as the staff and common areas can be characterized as classless. If you really want to be posh and have an enjoyable time where you can actually enjoy luxury in the city, I recommend you stay somewhere else.
