I stayed in Omny hotel in downtown L.A. It's is just excellent. Great room, huge bad, very high (they should consider to put an in room ladder to climb it). Breakfast is great service is very good.
As it's a working/office area there are many places to eat on lunch time. They are all closed by 6-7 P.M (except one bar-restaurant) and on week ends. Very close to Disney concert hall.
Otherwise, it's downtown L.A, not the best area to hang around in the evening although I did and felt ok.
