We do not have a Hilton hotel shuttle from SFO to the hotel, but you do have a few options that you can choose from for your transportation. The first option would be to pick any downtown San Francisco hotel shuttle from the airport and that will cost about $17 per person. Reservations are not needed and you would make the booking at the airport. You can also take the BART train (there is a station in the International Terminal) and get off at Powell St. Station in downtown San Francisco. Once you get off the train it will be a short 2 block walk to the hotel. This BART option costs $9.65 per person. The last option is to take either a Taxi or Uber from the airport to the hotel. These rides can cost from $35-50 per car and there will be signage at the airport for pick up locations.

We do not have resort fees, but we do require a credit card for a $75 per night incidental hold. This hold will be released at the time of departure from the hotel.

Cancellation policies will differ depending on the type of reservation you book. Check at the time of booking for the applicable cancellation policy.
