Yesterday I walked all day long looking for Santa Claus with my 3 years old son.

To follow the tradition, children need to write a letter to Santa Claus and give it in hand whithin the daysmail it before cChristmas.

I am not sure if you mean mail it, or give it to someone.

But Barcelona has changed a lot onin the last year.

The impact of covid ion a tourism based city has been huge: closed shops and empty streets are now the picture of the city.

However Christmas is magical and there are lots of activities to enjoy with childrens.

We spent 3 hours looking for a Santa’s letter, we wrote it and finally we give it in hand to Santa Claus.

This sentence doesn't make too much sense to me.. if you were looking for it, but then wrote it, it didn't exist until you wrote it?
again I am not sure what you meant by give it in hand - did you give it to a person? or mail it? or leave it somewhere for Santa?

A beautiful experience for a 3 years old kid who doesn’t understand noanything about covid.
