This is a strong 4-star spot. The location is super, on the coast very near the downtown, wharf, aquarium, ... lots to explore. The service for my stay was very nice. Room was clean. Conference food was very good. Concierge service is available and responsive. Restaurant is very good, and other very nice choices are within walking distance. If you are a runner or walker, you can run or walk along the beautiful bay coast path that is only a few steps outside the door. Really a nice place to explore.
One real standout for this hotel is their beds. They use mattresses made by "Monterey Mattress Company". I am not sure who they are (they advertise on a little card on the desk that one can purchase a Monterey Mattress after trying them out), but I can attest that the beds were absolutely the most comfortable of any hotel where I have ever stayed. Lots of high quality pillows too, which seals the deal for me. Comfortable beds when traveling are just a great surprise, never expected, and certainly not taken for granted!
