Dear ...

I would like to apologize (that) I could not say goodbye, but I was in a hurry. I am really thankful for the opportunity of being able to spend 3 months in Madrid, to get to know the culture, cuisine, cities/towns and sights. I hope you were satisfied with my work and that I will be able to return again. Thank you for everything once more.

All the best XY
