Hi Mary,
I would like to thank you for your service, for your kindness, for your understanding and for your help, which you used to offer to me before I had to ask for it.
You have a lovely house in a great location! The room is located from the backyard and is *very* quiet, which I didn't expected when I was booking it and what was a nice surprise to me -- especially, taking into consideration how close the place is to the city center.
Thank you and see you next (and each) time I am in Edinburgh :-)
