Just a great stay. Hotel staff is on point!
My wife and I traveled to San Francisco for a weekend to attend a conference and hang out in the city. We brought our two year old along with us to make it a family trip. We booked the room directly through the hotel website and got the package including valet parking (in & out privileges). Its not a cheap place to stay... but it is not exorbitantly expensive either. 
The service from the moment we arrived was awesome. The valet staff, doormen, front desk, etc, ..were all very courteous and helpful. The doorman even saw that I was about to leave my iPad in the car and asked me if I wanted that up in the hotel room -- which I did, and appreciated his observation.
The room was what you'd expect in a higher end 4-5 star hotel. Very clean, comfortable and luxurious bedding, polished and elegant bathroom. We requested a crib for our toddler and they provided an oldschool metal-barred crib. I usually prefer the collapsable playpen ones because the bars seem so cold and hard...but my kid didn't mind and they provided extra sheets to pad the crib with.
When my toddler and I were walking through the hallway to get ice ... he was very happy and talkative and one of the hotel staff noticed us...he asked what room we were staying in. That evening when we returned from dinner, a glass of milk and a plate of cookies was waiting for my son in our room. I thought it was a nice touch... really sort of set the tone for the whole hotel stay.
The neighborhood is surrounded by big buildings and is in a mostly corporate/business area. However, while walking with my kid outside, we discovered a nice little park about 3 blocks north of the hotel: "Portsmouth Square Plaza"...it seems to be in a Chinatown part of the city and was a pleasant place to hang out during the daytime while my son played on the playground equipment and in the sand.
Overall, we had a great stay with no complaints. Its a luxurious hotel no doubt..but it is the service that was most memorable.
