Paulina's podcasts (and the rest of the learning material that you can find on polskidaily.eu) really set the bar for language learning resources out there! Her stories are easily accessible at practically any level (I recommend the companion podcast Daily Stories and Talks for A1 and A2 levels), her enunciation is extremely clear while being natural (which helped me at the beginning when I struggled to recognise certain Polish sounds from other podcasts), but most importantly, they're extremely interesting! Paulina has a lot of interesting things to say about Polish culture (and not only), so you won't only improve your Polish, but you'll find out about many aspects of Polish culture that you would not be able to find out about on any textbook. Since I started listening to Paulina's podcast, and later on using the rest of the learning material on her website, my Polish has improved drastically. If you're either starting learning Polish, or if you're already at an advanced level and want to improve it, I really recommend it!
