Beautiful hotel, great service, watch out Internet fee
We stayed here in August 2012 and spent three nights at the Omni San Fran. This is an absolutely beautiful "traditional" hotel. It is very well maintained, the rooms are nice, etc, but you should not expect a modern hotel/decor. It is a high-quality hotel in the style of what I would describe as similar to the classic quality Fairmont (sorry to compare it to another brand, I'm just struggling to find the right terms otherwise) experience. The Omni SF looks, and makes you feel, grand.
The service was impeccable. We had an unusual request to bring champagne glasses, ice and a bucket up at a particular time, etc and it was done by the desk staff no issue. All the staff were extremely courteous and exceptionally knowledgable.
It was a special weekend for us as we got engaged so we'll always remember our time at the Omni happily.
The only thing I would say that was a negative experience was the Internet usage fees. I haven't checked but I trust they have it posted in the information book, etc, that there is a $10 daily fee for Internet. All that said, when you're staying at a high-end hotel in 2012, I naturally assumed Internet would be included and you wouldn't get nickel-and-dimed with fees. That language is stronger than my actual sentiment - I really loved my time there, but getting hit with a $40 or $50 extra charge for Internet didn't leave the best final memeory, unfortunately.
