Albergue La Estación has a good reputation, although it's a couple of kms out of town, so it's best to buy whatever supplies you might want for the next day on your way through the town centre . If you want reassurance that it's open, you could contact Badajoz Jacobea through Facebook or email **:

Failing that, there are beds at the sports centre, which is on the same road out of Campanario as the albergue (some distance before the albergue). I think the keys to the sports centre can be picked up from the Policia Local, across the road.
I stayed at an apartment ("Malay") which was listed in the guide in 2017. It wasn't very good. The owner charged me more than the advertised price ... and unsurprisingly it is no longer listed in the guide to accommodations.
** I recommend getting in touch with Badajoz Jacobea whatever you do .The association is quite active, as you will see from the waymarking and high quality albergues (except for the last stage on the way to Merida). They might invite you to meet them or to drop in at the school CEIP Ntra. Sra. de La Antigua de Mérida which is on the Camino as you enter Merida. The school is very proud of its place on the Camino, as you will see. They will welcome you if you drop by to fill your water bottle before visiting the Roman Circus next door:
