Question

Si no tienes mucho dinero, es mejor que ______ en un albergue. Son muy limpios y cuestan muy poco.

Is it duermes or duermas?

Answer 1

Duermes and duermas both mean "you sleep,"

But "duermes" is present tense,
and "duermas" is subjunctive.

Whenever we say "it's better that...." in Spanish,
we need to use the subjunctive.

And in this sentence, we can see that "es mejor que,"
means "it's better that."
