Colin's appartment is clean and very well located.
The small attentions provided (bottles of gin and whiskey, bread, eggs and jams, etc.) are very nice.
The sanitary facilities were clean and the bedding of good quality.
The documentation (books) on Scotland and Edinburgh were very useful.
Continue like that, do not change anything!
Congratulations to you.
