How to listen to podcasts (no question mark, since this isn't a complete sentence)

Listening to audio programmes, or podcasts, is simple if you have access to the internet. You just need to find a podcast platform or app that suits you and then sample some of the many thousands of podcasts made around the world. All podcasts are free, and most are available via many different apps.
On a website  (does this belong in another sentence?)

The simplest way to listen to podcasts is on a web browser like Chrome, Safari or Microsoft Edge. You can do this from a computer or from the web browser on your phone.

My favourite area

My favourite area is Malasaña, located in the center of Madrid. Its streets are full of life and joy. There (I deleted "also" because it is continuing the same topic) are many bars with all types of music and public (do you mean public as in "público" or that the music is public?). This neighborhood celebrates the Second of May* parties, one of the most important parties of the city.
For the next year there will be the possibility of what people and collectives from Madrid join their proposals to the festival program. For the next year, people and collectives from Madrid can submit their proposals to the festival program.

I wouldn't translate "dos del mayo" because it is a proper noun in this case -- a more natural sentence would say "This neighborhood celebrates the parties of dos del mayo, or second of May, one of the most important parties of the city.
