I relocated overseas a while ago, and began with DuoLingo, a Michel Thomas Method audiobook for complete beginners, and a short course on Coursera/FutureLearn/EdX (I cant remember which one) before I arrived. Between these three resources I managed to test into an A1 level class in my new country rather than one for complete beginners.
The class followed an intensive three month course, and at the end I had a lot of confidence and progressed quite quickly from there.
I returned to DuoLingo to finish the course because it's great for vocabulary, but with the listening exercises switched off, because by then I'd learned that the computer-generated pronunciation of my target language was really off. I still use DuoLingo every day, usually to practice grammar points that I don't completely understand, but mostly because I'm protective of my streak 
I started watching children's tv shows on Netflix in the target language, and worked from there. Podcasts have been good for getting to know some of the country's different accents. Listen to the radio news, with the station's homepage open so you can read as you hear and pick up cues from images. You'd be surprised at how much vocabulary you can soak up quickly doing this!
When watching tv in English, I turn on subtitles in the target language as I find it's a great way to better understand its syntax rules.
There's also some great YouTube channels, run by language teachers. Spanish is about a million times more widely spoken than the language I'm learning, so I imagine you'll have plenty of choice there!
Good luck OP, and have fun!
