Not a business friendly hotel
If you need to come to San Francisco or work reasons... stay far away from this hotel. Hilton is so concearned with collecting $10 per day, per device ... that they have forgotten to provide quality, always on internet access. Sending an email can take 20 minutes... downloading a file can take an hour... if it it works at all! Printing any document will cost you... money and lots of time. It would be cheaper and faster to buy a printer in SF and through it away when you are done.
Hilton should be embarrased for having this badly run property with its name on it.
