We liked having a lockbox instead of meeting the host so we could arrive whenever we pleased, we had a leisurely drive from Inverness instead of rushing to make it in time through traffic. It was really useful have a washer AND dryer although beware using the dryer late at night because the neighbors can hear it (sorry neighbor!).
The touch I thought was so lovely was having a mirror right on the windowsill, it was a lot of fun to sit by the window and do my makeup in natural light before we went out. There were things for coffee and some bites for breakfast as well. We would have been very comfortable to stay longer if we didn't have other plans.
