I’m a Spanish language learner and I know how tough it is to find a good language partner. Are used to use italki, but they eliminated their exchange feature and now they only support tutoring and lessons. I found this though which seems interesting and I think I’m gonna try it:

> Many people who use Couchsurfing are searching for a place to sleep in a foreign city. However, what’s lesser known is that the website can also be helpful in finding language partners. The majority of Couchsurfing members don’t actually host, but rather have their status set to “Coffee or a drink“. In the advanced search function you can find potential language partners simply by selecting your current city and setting “language” to your target language (in this case German). With over two million members on Couchsurfing, success is very likely. Plus, it’s free!

Maybe it’ll work for you too
