I once paid a guy to walk around the city with me to teach me Spanish. We would meet for a coffee and from that moment the conversation was entirely in Spanish, and he would grade the complexity of the lesson according to my ability. As we walked around I could point at things and ask what they were and he would explain. I remembered much better than in class because I had associated the words with the walk.
