Not what should be expected of the Westin brand, SPG take a close look at this properties management!
Stayed 2 nights through Memorial Day weekend along with another couple, 2 rooms connecting both king beds on floor 9.
From the moment we pulled in to the driveway we felt like this might be a less than satisfactory stay. There was a cluster of activity going on and it seemed like the valet staff were not able to handle the volume of cars or people. We waited in our car, running for literally 10 minutes before we were even noticed and asked to pull up, nobody offered assistance with baggage nor anyone to open the door as another member mentioned. Swinging door was broken the whole stay.
We were fortunate to get to the front desk for check in before the mad rush came and were checked in my a very nice young woman who didn't go through the standard procedure I had expected as an SPG Platinum Member(not earthshaking but surprised non-the-less). No upgrades and was told they were oversold, hint that this was going to be a rough stay. Asked if rooms had mini-fridge, was told they did not, asked for one in each room was told no problem if available. 
Up to room finding that hotel showed signs of age and in need of help, scuffs on walls, carpets worn and torn, slight odor as we walked to our rooms. Rooms were typical Westin style, clean lines and nice comfortable bed but age shown. Found that each room did in fact have fridge and would have told the desk this IF they ever followed up on it but no call about availability of fridge(ball dropped). 
Went back down to valet because my wife left tablet in car, what a scene down there. Slammed front desk and valet, worse than before. Waited like 10 minutes for someone at valet to assist, retrieved tablet and overheard some very unhappy guests grumbling about slow services, incorrect reservations and other miscellaneous gripes.
Went down to ask concierge for suggestions on places to dine as it was getting late and we were hungry, she was less than enthusiastic or helpful, ugh!
We chose to just eat in hotel as it was getting late and the ladies were starved, BAD CHOICE! The place had maybe 5 tables when we were seated, there was 1 server for the whole place and seemed like some management helping delivery drinks, she was slammed and it showed. We ordered simple menu items, salads to start, burgers for meal and cocktails, caesar salads had absolutely no taste, burgers were weak and fries soggy and limp, no follow up for second round of drinks, no follow up at all actually. The family sitting right next to us got a round of drinks and nobody back to take order so they up and left in disgust. We should have done the same, bad choice to hang in there. I was later told that they sent home the additional wait staff because it was slow, oversold hotel but slow, cutting servers by 7-8PM????? Are you kidding, on a holiday weekend to be understaffed!!!!!!! I was boiling! 
I knew that the rest of the stay was going to be rough so after we ate I sent the other's to the bar for a follow up cocktail and I went down to talk to the MOD, Carrie Harrington was on duty and gave me her ear offering to cover parking or anything that would make the stay better. I told her it isn't about the $$$, it is a blown first impression. I had encouraged my friend and his wife to join SPG, explained how Westin fits into the chain and it's level of quality all of which were the complete opposite here. They blew it and it didn't get better as the stay went on.
The phone would ring at the desk sometimes literally 25 times and sometimes nobody picked up, they were understaffed in all departments the entire weekend. 
Gym was nice but gear getting rusty and a bit warm, no circulation. Ran out of sani-wipes, called to request more and nobody picked up the emergency phone line, um ok so I used the line for wipes but what if there were an emergency....fend for yourself?????? 
I could go on forever at how bad this Westin was but if you choose to go anyway you will see for yourself, at least until the rectify the situation there. I travel 150 nights a year, if you don't want to trust my opinion go and find out for yourself.
There are a lot of choices in DC, make another one for now please....do yourself a favor.
