Going on Erasmus is taking a leap into the unknown. And to be honest, the first weeks were not as fun as I thought "The Great Erasmus Experience" would be. But that changed quickly, I found friends for life. I partied, went to museums, studied and travelled with them. Back in my home country, we're still in contact and had a reunion already in Paris!
Rome is literally a free outside museum. My apartment was really close to the Vatican but every time I walked through it I had the same happy feeling.
