After one month in Spain I would say that I learned quite a few things.
First would be that I learned to take care of myself for longer periods of time. I had to watch over how much money I spend, how to wash clothes, clean and other stuff like this.
Second i learned that people from other countries can be very different than those in Slovenia. And that communicating can be quite hard if most of the people dont speak english, so the translate app came in really handy. I would say my english improved slitely.
The last thing i would mention is my navigation and orientation skills improved. Madrid is a big city so it was really hard at the beggining, but last week it was already simple to get around and on what train to get where to get off and things like that.
It was a great learning experience. I would recommend it to everyone.
