The description of Alan's place matched reality perfectly, I'm glad to say. The apartment lies in a secluded building with a courtyard, so it's quiet, but still lies right behind the Royal Mile. You'll have to walk a steep "close" (small street) to get to the Royal Mile, but then again: Edinburgh is quite steep all around.
The apartment itself is really clean and tidy and it has a cosy atmosphere. There's a nice kitchen, ironing board and washingmachine. The bathroom is clean and well-lit. The bedroom is small, but the bed is comfortable. I absolutely loved it.
