Good location
This was the worst hotel we stayed at during our trip in America, it was also the most expensive. The rooms were small, poorly equipped (my hair dryer kept burning out, no coffee maker). It was really noisy due to the location being right off of Union Square. It was a little annoying waiting for the tiny lift which was also very slow to go up and down the 8 floors. We left quite late in the morning due to sleeping badly which meant we missed having our room serviced our whole stay. 
The staff are friendly and attentive.
San Francisco is crowded and run down. I didn't feel safe walking around at night, more than once we found ourself walking down streets feeling completely scared. We struggled to find anywhere nice to eat. I would never go back.
