What a quaint hotel!
my husband thanked me several times for "finding" this place.
for our 10th anniversary, i wanted to celebrate in french style, to commemorate our honeymoon to Paris.
we were very pleased. it's not your typical chain hotel. come here for the boutiqueness & quaintness!
the check in staff was helpful. he brought us to our room (it has a real key) and made sure we were comfortable. told us about the city, gave us a couple of tips.
the room is small, but big enough. lots of closet and storage space (which we didn't utilize, as we were only there one night). 
we surprisingly slept very comfortably. we kept the window open and listened to the sounds of San Francisco until about 6am. it became a little warm/stuffy, but we were able to go back to sleep.
the only drawbacks are the above-mentioned no AC and the tiny bathroom with a claw-tub/shower combo. there was no vanity or counter space, so getting ready was a little tricky. nothing i would deter me from staying, though.
we were really happy with the hotel. breakfast was small (but perfectly portioned; not "american-sized") and tasty.
also, they were gracious enough to store our luggage when we checked out, knowing we were going to be exploring SF the whole day.
oh! and it was a perfect location on Bush St.
