Translation of pensionieren

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!
Sunday is fine. Please let us talk tomorrow to arrange a schedule of that day. I will call you tomorrow, but in any case, here is my number again. We could do it also on Monday next week, if it fits everybody.
As usually, we had problems with our hotel. At midnight we checked in to our place, and once seeing the room, my wife decided that she would not sleep there. She was right, it was a place with no atmosphere.
