Dear Mr. and Mrs. Keer:
We just arrived at Hidden Hollow today, but couldn't wait to thank you for the warm welcome we received. We really appreciated the coffee, jam and wine, as well as the sunflowers and hydrangea. Most of all we are so impressed by your beautiful home, and the pains you have taken to make guests feel at home.
My wife and daughters join me in thanking you for going above and beyond our expectations. We're already thinking how difficult it's going to be to leave!
