Bank account in Spain

Hello guys, I need a little help regarding the banks in Spain. I am already in Spain in Tenerife to be more specific and I am doing an internship. My workplace wants me to open a spanish bank account and Im not sure which bank one would be the best. They say Caixa or BBVA ar the best. So I am writing here to ask for your opinion of which one would be the best for an internship as student who only use the bank account for around 6 months.
