Great location, service uneven
I stayed here for one night before my international flight. W's are hit/miss in my experience. I am Starwood Gold and was upgraded one category and my amenity was internet. The internet worked well in the room and public spaces. 
The property is in a great location (a block from white house and walking everywhere else). I was greeted by bell/door staff and escorted to check in desk. My check-in was fairly quick and friendly. My room faced the street and was quite quiet - i didn't hear any outside noise. I really liked the feel and decor of the room - the sink is outside of the bathroom and while i am not a fan generally, this worked well. I did need to have housekeeping change the sheets as there was a hole in the sheets - the front desk arranged this while i went to eat at the rooftop restaurant (or thought i would eat in the roof top restaurant).
It was 3pm and i wanted a late lunch having just arrived in town - i went upstairs to the restaurant and it was quite empty and figured no problem to eat. I was behind a family (tourists not staying in the hotel) of five and the hostess said "everything is reserved" but if you can be out in an hour i can seat you there. They said yes and were seated. I was next and said "party of one" and was told there was no room as everything was reserved - I queried why seat them and not me? she said people had reservations for dinner which was much later and i could try to find something in the bar area. I asked again, how at this time of day with more than ten tables empty she could not allow me to eat lunch as a guest in the hotel - she was stone faced as if this was a velvet roped restaurant - i just wanted a club sandwich and would be out in less than an hour. she didn't budge so i went to the bar to check it out - it was full - no space for one - i was starving! I could understand if the restaurant was reserved for a wedding party or other event but would expect to be told so at check in or see a sign about a private party - this was just the hostess pretending she was important rather than looking at the good will of paying customers that she has now given them reason to stay elsewhere.
I was quite angry by this - i was a hotel guest denied lunch and walk-ins were given a table - how does that make sense? you are basically saying go outside the hotel and give someone else your money (had i known how close the Corner Bakery was i would have gone there) another couple ahead of the family had also been denied a table so i went to the front desk and requested a manager to see if this is standard policy -the manager had just arrived and apologized and said no it wasn't their policy to deny seating as the restaurant was open for business and he would look into it (he never came back to follow up with me)- he said i could eat in the lobby bar - i wasn't thrilled wtih this but he introduced me to the bartender and she was lovely to chat with (she looks like emma stone!) and i ordered the famous club sandwich, glass of wine and chatted with her for a bit. Then the rains came and the empty bar area swelled to over 100 people in less than 10 mins - the bartender did her best and then reinforcements (three staff) came to help out - this is how a hotel should run - accomodate guests and move staff where most needed. when i went to pay, I was told my meal was comped by the manager.
I tried to use the Acura local car service to take me to my friends apartment which wasn't that far but i hadn't booked in advance - it was a service i was unfamiliar with but the in-room ad was helpful that i will try to use it another time - the bell staff was very apologetic that they couldn't help me -with the rains, it got booked quickly. another time.
Upon return after dinner, there is a velvet rope for the nightlife aspect of the hotel with a separate elevator. I showed my room key and was let in quickly to the hotel guest elevators. 
So like any other W - be prepared for a hit/miss stay - some highpoints and some low points - if you know what to expect you can't be disappointed. Going forward, i would use cash/points option to stay here, won't pay full cash again or have my employees stay here as there are many other properties that cost less with a better overall experience in the area.
