Comfortable and luxurious
I was in Los Angeles on tour with an orchestra playing at nearby Disney Hall, so very happy to be based a very short walk away. As we would stay in LA for our concert up the coast in Santa Barbara and had a free day in the mix as well, I had four nights at the Omni. For a large, corporate hotel, it is better than average and less generic than similar accommodations. The rooms were large, spacious and comfortable. The rooms had everything you would expect from a top hotel including robes, plush towels, a safe, and numerous television channels to help while the hours away if you could bear to be indoors! The hotel was impeccably clean, the staff genuinely helpful and friendly. (I might add the never ending sunshine didn't hurt either.) I had a coffee with friends on one of the outdoor terraces - delightful.
My only criticism was that my room was connected (by a locked door) to the adjacent room. This seriously compromised the sound proofing of my room (and I imagine the other one as well.) I could hear every word of telephone conversations, the television etc etc. As the noises from the hall were quite present as well, I was happy to have brought along some high-quality ear plugs (available at most airport and better than what you will receive on the plane.) This may seem like a trivial matter but getting rest without disturbance is part of the basic service a good hotel should offer. I would return but perhaps ask for a quiet room ...
