Spaniard who want to live in Dublin needs help

Hi! I've been living here for 4 years (came from Madrid). My situation was a bit different cuz I moved with my whole family, anywho. For courses and stuff like that you should go to community colleges, they usually have a big range of courses available. I'd point out some places but it's best if you go to a school closer to your area, the only thing is that they usually start in september.
How long are u planning to stay for? There's A LOT of spanish people here but to learn english is better if you share an appartment with or rent a room with an irish family. Also I know it's easier to make friend with people who speak your own language, but you'll learn faster if you make friends with people from other nationalities.
You can also put ads in shops looking for people to help you with your english, and in exchange you'll help them with spanish.
I don't know about other places, but in the library in Lucan, they have this groups that get together to practice different languages such as english, spanish, french....etc, and it's free, you just have to call up and give your name.
Hope that helps you a bit
