The host was very nice and welcoming. I arrived a day later than I booked because I was focused on the date I was leaving the U.S. and not on the date I was arriving into London.
The host didn't mind that my son who is living in a small UCL dorm room near by, to stay there for the night. He called immediately and said "mom you are going to love this place"! He cooked dinner for himself and took a nice hot shower. A real treat!
