Hi, my name is Fran,
I am children teacher (Maths, Natural Sciences, English... and Spanish too) and love my native language. I have wroten some poetry books, and studied journalism and audiovisual communication. I read a lot in English, but maybe my writting skills aren't the best...
I don't know if i will often use this platform... but two years ago, I started to record audiobooks. Maybe some o those will be difficult to understand, but there are more than thirty... so you can choose according to your level. There are some books wrote in old Spanish (Lazarillo de Tormes, Mío Cid, El conde Lucanor...) what I don't recommend for starting. For beginners, I recommend children books, like The little prince (El principito), Alice in Wonderland (Alicia en el País de las Maravillas) or Jonathan Livingston Seagull (Juan Salvador Gaviota).
Also I have published some long novels, like Frankenstein, The truce (La tregua, maybe a good option because it is written like a diary), 1984, Hiroshima's notebooks... and short tales; The black cat (El gato negro) and other stories written by Edgar Allan Poe, Ray Bradbury and Isaac Asimov (sci-fi).
You have other options; the most popular are Librivox ( https://librivox.org/ ) and Albalearning ( https://albalearning.com/ ). It's hard to find free audiobooks in Spanish... but there you can find a lot of different narrators, from different regions. Also you can look for audiobooks in Youtube, Spotify and Itunes.
Some interesting youtube's channel are "Pepe Mediavilla" and "Joan Mora". These days, youtube was deleting audiobook's channels... so the most of the content are audiobooks read by computer software.
A podcasting platform for Spanish speakers very popular is Ivoox ( https://www.ivoox.com/ ), and there you can find also interesting content.
In any case, you can ask me something you want to learn about Spanish. I can explain better in Spanish, but if you can understand this text (it isn't perfect, I know...), I will can help you in English too.
And, If you are Spanish teacher, I would know about your experience with this platform, and maybe I will join also like professional teacher, who knows! ^^
