Translation of Martian in Spanish

We would love to have you here as our guests! My niece Katja had also many diffculties with the new surroundings. She is really upset with this new change. How was your trip to Italy? I'll keep writing to you!
Nevertheless I think that we need to communicate. All in all, we will learn a lot from each other, mostly by writing, but speaking exercises are also really good for your Spanish skills. Is this OK?
By the way, after my horrible experience I had changed the hostel. The place was not really better but much more quiet and near the Ocean. I woke up with the sound of a siren. It was the police.
