Chic but not practical.
Simply put the SLS tries too hard to be chic and ends up being unpractical. The mood lighting and funky decor works in the lobby and hallways but it just doesn't work in the hotel rooms which are small and overly dark. In fact, they are so dark that I found myself crouching by the window to do my makeup each day!
On a good note, the pool is nice and the gym is big and beautiful. The food in the cafe is very good but very overpriced. The best part of the hotel is the on site restaurant Bazaar which is absolutely worth visiting. 
I do like be location which is right near the Beverly Center...but just cannot get over the dark rooms which after a few days get very depressing.
