What you can expect from this couple is an amazing sense of home away from home. It is a cozy and quiet place, with an unrivaled view of Holyrood Park from its windows. To those who like to wake up every morning to a beautiful sight, look no further and book this; while I was there, I saw the beauty of Holyrood Park when the sun was brightly shining, when it was covered in a eerie fog, and when it started to be dotted with yellow gorse. For short term travelers to Edinburgh, this is an amazing location if you want to find something away from the hustle and bustle of city centre, while still being very accessible to it via bus (~20-30 min), or walking (~40-50 min).
As for the hospitality of this couple, I have never met any host on Airbnb that can match them. They helped make Edinburgh become a comfortable home for me during my few months stay. They are always happy to talk to you and are great to converse with. If you need any help or additional supplies, they are happy to help you out - just talk to them! My only complaint is that Edinburgh is so far away from Canada, that I cannot visit more often.
