I left Portugal in 2020 to be one semester in Lyon, France but I actually ended up staying 11 and a half months. This happened because I met French people that later became my friends and family!
Everytime you are able to integrate someone that is doing erasmus, please do not hesitate. It means the world to each one of us. When I was integrated in France I did feel on top of the world because I was having fun with locals.
