Narrative:

The captain had just made the prep for arrival announcement. I had made the first announcement then walked to the first class curtain while tying up the curtain I could smell something acrid and electrical. As I stood there for a second I thought about it and started walking back towards the forward jumpseat and the captain was called. He asked if we were smelling something and I gave a quick yes! Told him I was just at the divider and smelt it as I was walking forward as when he called. The capt. Then asked us to double check the lavs go through the cabin see if we can find out where it's coming from. I could mainly smell it stronger at about row 11. As I walked over to the back I had another flight attendant the B flight attendant walk forward with me to smell up where I was. He wasn't smelling it as much in the back nor as strong as I had initially sensed as if the smell were slightly dissipated. When coming to the front again the captain called again to verify some things such as if there was a visible smoke or visible indicator of the smell which I could not confirm. I could smell it coming through the air vent. The B flight attendant could smell a different smell coming as well. At this point another the D flight attendant had gone into the lav and there was a burst of an odor again but this time seemed more promininet. The captain then said he was going to start going through checklists and will advise and for us to be vigilant. I made the call to do final at that moment so we could focus on the odor and be ready for any indication/instruction from the captain. I went through the cabin again and this time the C flight attendant confirmed the strong odor through the vents in the back galley. I also got eyes on the engines from passenger seats to then see if there was any visible indicator and there wasn't any. We were receiving several glances from passengers as they could tell we were tending to something but no pax reported any irritation; but could tell we smelt it already. The captain called again to confirm for us to turn off the lighting; and to turn on our galley work lights and pax reading lights as necessary. The captain began turning off masters for lighting etc.. After different things were powered down the smell dissipated and we were well below 10;000 ft. By the time there were no more odors. When it came to lighting; the captain had said we can turn on passenger reading lights as needed however since it was mid afternoon and sunny with plenty of light to see I did not advise the rest of the crew to worry about overhead lighting as I felt it would unduly raise more questions from passengers and as well as comparable to as if we were in an 900 on landing with all lights off.
