Narrative:
On the last 1000 ft of climb up to FL250 we had a pressurization failure. We notified ATC and declared an emergency. We started a descent. ATC did advise to stop at FL210. We continued descent to FL190. We had set 12000 ft in the alert system. This was the altitude that I wanted and expected. This is what I felt was the lowest safe altitude. The captain and I did not confirm the 12000 ft set. It was loud from the breathing through the oxygen masks. We leveled for 1 min or 2. Then ATC gave us lower. I think that ATC should have given us a direct descent down to 12000 ft -- we were an emergency aircraft. Also; we should have confirmed the altitude setting.
