Approaching ZZZZ en route to our destination at cruise and just prior to top of descent; a significant acrid smell was noted in the cockpit. Oxygen masks were donned; crew communication was established and the Smoke/Fume/Odor QRH was initiated. It was verified that the same smell was noted in the cabin with no smoke or fire. As the checklist was completed the smell quickly dissipated. An emergency was declared with ATC; we gave our condition and asked them to stand by. At this point a SATCOM call was placed to Dispatch. After conferring with Dispatch and Maintenance Control; we gave our intention to divert to ZZZZ which was now behind us. Dispatch checked the NOTAM's and informed us that the runway was temporarily closed for maintenance. Based on our current location and with concurrence with Dispatch; we decided that our destination would be our best option. Communication with ATC was a bit spotty; but we were cleared direct to the ILS IAF at our best speed and a clearance to descend at pilot's discretion was given. The flight attendants were briefed and an announcement to the passengers was made concerning our condition and that a normal landing would be made. We landed about 33 minutes later without further incident.
