I stayed at One King West on a Saturday night in January and I had a very pleasant experience. It was my friend's birthday and we wanted to celebrate at dinner nearby and then head back to the hotel with our friends for cake. Unfortunately, the hotel has a very strict policy on the number of people that can be in the room at once. There's a max limit of 4 people and we had way more than that. We tried speaking to the front desk but they wouldn't budge, they said it was because of inevitable noise complaints and fire code restrictions. Understandable.
Other than that, our stay was very pleasant. Access to the elevators is restricted to key card only after 8pm so its safe. The room itself was very clean when we checked in and had no weird smells. It was a large room as well, with a double bed, kitchen (stove, dishwasher, mini fridge) and a bathroom with a stand-in shower. There was also an arm chair in the corner of the room by the windows with a lamp (cute spot to take pics haha). One feature my friend and I enjoyed about this room was the number of mirrors in the room. There was one by the table near the TV, a large floor length mirror by the door, and the bathroom mirror plus an extra zoom mirror in the bathroom. It made getting ready very easy.
Also another point to note: Plenty of outlets in the room, very handy!
