Kate is the perfect hostess, doing everything and little more to give you a pleasant stay. If you have any difficulties she will try to help you as soon as possible. The only reason why I did not give 5 stars is that I found my room a bit cold, however this was the standard everywhere I went in Scotland including my work so it is certainly a matter of general standards (in Sweden we have general heating set at 20 degrees 24h).
I would really like to recommend her fathers Highland tour, a day with car around Scotland. Colin was super and had a great knowledge about the areas we visited. I brought my mother and father who enjoyed it as much as I.
