HORRIBLE since the hotel left Joie de Vivre
I was a frequent guest at the Adagio for the past 3 years ( over 30 stays a year) and it was my favorite hotel in the City, until now. I recently stayed and found the staff less than welcoming and accommodating. It was SUCH a disappointment. The renovation looked good, but certainly not worth the extra $80 per nite price increase. I used to get a complimentary split of wine when I checked in with JDV...I asked if the new ownership did the same and the response was a sarcastic..."Uhhhh...not so much-- different management!"
The valet was no where to be found for 10 minutes, so I had to park at the indoor lot next door--not bad, as it was only $25. The old hotel under JDV would match that, if I valet parked with them (instead of the $40 that they normally charge) but when I checked out, I asked if I came to stay next time...would they match the $25...and of course, "No, that's not an option".
Upon check in, the front desk staff never asked if I needed to know anything about the new hotel/restaurant/bar/amenities, or the area .In fact, the check in and check out staff didn't seem to care if I was a guest there at all and never ONCE thanked me for my stay. 
Ridiculous--a huge amount of customer service training needs to take place there if they want to retain customers.
The gym was unkempt--dirty towels and used water cups everywhere. And...there was a nasty stench of cigarette smoke coming in thru the vents (with the windows to outside closed)! Not what I want to breathe in when I'm exercising!!
Overall...major disappointment. I filled out the online survey AND sent a personal email with the same concerns noted to Nathan the front desk mngr and Suzie, the GM...didn't hear back from them for a week, but when I did, I was offered a complimentary night's stay.
I definitely missed the JDV hospitality that is evident and consistent in every one of their hotels. New management at the Adagio has big shoes to fill, in my opinion.
