Stay somewhere else
Huge mistake, dont stay here as there are much better options in SF & in this part of town. We are staying here to celebrate our anniversary (our reservation is for FIVE nights) and this is what we are experiencing:
Huge disappointment. Long line to check in & only one person working the front desk. We had to carry our own luggage from curb to front desk & no one helped us with the front door. It was pouring rain & our luggage was soaked, & we were exhausted after 8 hours of travel. We asked the bell man why there were not more people helping at the front desk & he replied that it was our "timing", & that the other 2 staff members were "downstairs eating". We checked in around 5 pm.
Our first room was tiny, no closet w just a small armoire & the view was of a brick wall. The furniture was run down & the king bed sagged on each side where people have slept, there was a nice hump in the middle. The bathroom was the size of a closet. The second room was similar, too small but at least had a view. We asked for an upgrade & all they had was a junior suite w two full size beds. They told us we could move the next day (today) to the suite next door that has a king size bed. 
We spent the night in the jr suite w the full size beds with the idea it would be for just one night. The carpet was old & worn & stained, the furniture old & scratched & the middle drawer of the dresser broken. There was a piece of chocolate lodged btwn the carpet and floor boards, and the floor boards were covered in a layer of dust. When I was looking for a place to plug my cell phone in behind the dresser that was located btwn the two beds I found an old empty coke can, candy wrappers & lots of dirt & dust. There were hairs on the bathroom floor (which looked very dirty, white tile) & my husband found a dirty washcloth dried to the curtain rod when he got up to shower. The beds are uncomfortable & need to be replaced. There are no coffee makers in the rooms. They do serve coffee in the lobby in the morning, but I personally like drinking my first cup in bed while still wearing my pajamas. Especially on vacation! 
This morning I went to the front desk to find out what time we would be able to move to the suite w a king sized bed. They were perplexed as there was "no notation" in their system indicating we had been offered this. A manager was brought out to assist and all she offered me was a DOWNgrade to a smaller room that had a king bed. She said it was bigger than the original rooms we were shown & that it had a walk-in closet. I looked at the room before committing to it, it was small, same size as the others, the closet TINY (NOT a walk-in, not even close) & the bathroom was about the same size as the closet. when I called to let her know it was too small, she offered me nothing other then that she would "let me know" if a jr suite w a king bed should become available during the course of our stay. That was it. We are stuck in a dirty, run down room w 2 full size beds. We are not being compensated in in way shape or form, nor were we offered a complimentary upgrade after all we had experienced. This angers me especially after reading another reviewers report that they were upgraded to a corner suite for no reason other than that were members of s frequent traveler program. 
The lobby is beautiful. If that intrigues you, just come visit this hotel, but don't stay here. There are so many options in SF, & I would highly suggest you check those other options out. I really wish I would have, and I wish I had given more credit to the negative reviews I read about the Palace Hotel when I was making our reservations.
Honestly? The Courtyard by Marriott I stayed in with my kids a couple of weeks ago in Chattanooga TN was much nicer, beds more comfortable, coffee machine in room, and CLEAN.
