I am an Accountant and my wife is a Theatre Actor/Director. We have no children but instead have 3 fur-kids.
Cat and John are very nice people, respectful and friendly. We stayed in touch before and during the stay. We really enjoyed helping them preparing their trip. When we got back in our flat we were under the impression that nobody ever stayed there ! The only clue was the lovely note posted on the fridge :)
Don't hesitate to host them!
