Everyone here has some great suggestions but as far as I can see no one has mentioned the Michel Thomas courses. I have found his way of teaching quite smart especially if you speak English. I mostly listened to his course and practiced a bit with Duolingo(didn't find it that helpful but it was ok) before going to Spain, and I have to say Michel helped me a lot in recognising structures and phrases. If you combine it with learning some vocabulary it'd be really good.

But as most seem to say and I have to agree, the best thing to do is find people and speak the language as much as possible (native speakers, tutors, other learners).

I second the Michel Thomas recommendation. What it gives you is a good ear for more complicated grammatical structures. There's no getting around putting in the work to build your vocabulary, but it really helps bridge the gap between the grammar rules you read in a book and recognizing and using them in conversation.
