Sam is a great host, provided loads of good info before and during the stay. The place is exactly as you expect from the listing, kept clean and tidy. There's a few house rules to bear in mind with doors, noise, shower operation etc, but all easy enough to wrap my head around.
Sam sent a number of recommendations and written tour guides, I followed a couple of these and had some exceptional walks through Edinburgh. Sam also provided info as and when, eg info on how to book at the castle, lockers in town where I could store my bags on my final day, etc.
The location is GREAT for quick access to Arthur's seat, Royal Mile etc.
All in all, an exceptional and great value base of operations for my stay in Edinburgh.
