Communication with Kitty was always efficient and businesslike - and we were met by Angus who talked us through the amenities.
The apartment was spacious, comfortable and well-equipped. A comfy bed, soft towels and reliable wifi are all examples of the great attention to detail. There's a good working kitchen (even sharp kitchen knives!) which has some of the basics (tea, coffee, herbs, spices, etc.) left by previous guests.
Location is excellent, away from the bustle of the main streets, but with the large shops on Princes Street and the entrance to Edinburgh Castle only 5 minutes walk away. There are lots of good restaurants with a range of prices within an easy walk.
For anyone with mobility problems, it's worth noting that the apartment is 2 floors above street level and the building has no lift.
Oh - and the image of the castle on the website is actually the view from the lounge window. It really is that dramatic.
The important final question is always "Would we stay there again?" The answer is undoubtedly "Yes."
