Turn the bathroom fan on
First tip on staying here. Close the bathroom door and turn the fan on. Hopefully that will prevent the smoke alarm from going off. I wouldn't know - I didn't do either and ended up dripping wet, naked, and frantically trying to turn off a horrendously loud smoke alarm. I suggest detaching it from the wall and throwing it under the mattress. When I called the front desk to let them know it seemed like they were well acquinted with this problem - probably happens daily there. 
Beyond that, hotel was ok at best. My non-smoking room smelled of smoke. I know modern design is a cool thing at hotels and tend to enjoy it, even if I wouldn't decorate like that at home. I've become a big fan of W hotels. This is not that. This is the least practical hotel room that I have ever stayed in. I didn't watch TV, but the fact it was on the floor off to the side didn't really make me want to deal with it. The bed platform is quite a toe-stubber, it seems to be everywhere. I personally don't mind the glass bathroom but I could see it bothering many others.
Should I have to stay in DTLA again it will not be at The Standard.
