Thumping, Disinterested Staff, and A Restless Stay
This was a very poor experience.
When I checked in, the front desk woman was friendly and helpful. The service went down from there.
This was a business trip and I had arrived to SF mid morning after waking up very early so I was looking to get to sleep around 10pm. Since I was on the second floor, I figured I was far enough from the street noise. I was. But, I was pretty much on top of the nightclub.
So, until almost 2am, my windows shook and the base beats of the night club kept me up. It was very very loud. I called down to the front desk and was told that the music would end around midnight. So I was patient. Then it was 1230, then 130am, and the music kept thumping.
The person on the phone was abrupt and rude. I asked my question, she answered, and then she hung up quickly. I'm guessing she was getting lots of calls from angry guests.
It was impossible to sleep. This was not something earplugs would block.
The next morning, working on a few hours of sleep, I asked the front desk to change my room. 
There was no apologies, no explanations. It was just a cool and unfriendly greeting, that did end up moving me to the 4th floor. The guy behind the desk didn't seem surprised about how horrible my night was. He didn't really care either.
So, the second night started the same: enter the shoebox sized room and hope for the best. At around 10pm, I start to hear a faint thumping beat. It's 2 flights above and I'm still hearing the nightclub!
I was able to doze a bit as it was a bit less than the night before but it was not a restful sleep.
The hotel in general is not worth a stay, it's cheap but not worth not sleeping. The location is fine but the service and comfort is lacking.
