Arriving and leaving

At check-in

Cancellation and deposits

Our house policy is that a booking may be cancelled by 3:00 PM local time three days before arrival. Later than that, one night is charged.

Non-refundable rates cannot be cancelled or changed, and the full stay is charged. Some rates require full payment at the time of booking.

Cancellation, deposit and modification terms vary by rate, and the terms shown when you book always take precedence over this page. Read them before you confirm.

Smoking

The hotel is entirely non-smoking — all 131 rooms and every public area. This includes vaping and e-cigarettes. Cleaning charges apply where the policy is not observed.

Pets

Pets are not permitted. Service animals are welcome in accordance with applicable law and are not subject to any charge. Please tell us in advance if you are travelling with one so we can help.

Parking

There is no car park at the hotel and no valet service. The Union Square Garage and the Ellis-O’Farrell Garage are both a short walk. See getting here.

Rates and taxes

Rates are quoted per room, per night, before tax. San Francisco occupancy tax of 17.7% is added, together with any other applicable local assessments. There is no resort fee and no daily amenity fee at this hotel.

Damage and conduct

Additional charges may apply for damage, for cleaning beyond the ordinary, and where hotel policy is not observed. We reserve the right to refuse or end a stay where conduct affects other guests or our staff.

Special requests

Bed type, floor, room location and connecting rooms are requests, not guarantees. We will do what we can. If something is a requirement rather than a preference, call us before booking and say so — see accessibility if it concerns access.
