Chicago hotel recommendations

Hello, planning a two night trip to Chicago and looking for hotel recommendations. Would like it to be on magnificent mile and 5 stars. Previously stayed at Waldorf Astoria and had a bad experience, so looking for other recommendations. Not looking for a suite since it will just be two people, but most important is nice bathroom, view and lobby ambiance. We will be going beginning of December so huge bonus if any hotels decorate for the holidays. Thank you in advance!
