The evening I arrived in Edinburgh I met Charlotte in the apartment; she had the heat on (it's cold in Scotland!), bread'n'butter basics (delicious!) and gave me the grand tour. And grand it was! This apartment is constantly booked out, and I can totally see why.
The location is ideal (5 minutes walk to the Royal Mile, 20ish minutes walk to Waveryly Station) and it's situated above a delicious coffee shop and an array of restaurants and grocery stores.
The furnishings are beautiful, unusual and comfortable. We were staying the weekend for a wedding, but decided to spend a night in just to enjoy the calm atmosphere. The shower facilities are ideal and we made use of the iron, hairdryer and dishwasher. Prior to our arrival, Charlotte had a great list of things to do/see/eat/drink in Edinburgh, and I've never felt so welcomed to stay anywhere else.
I really cannot recommend this location enough! If it's not totally booked out, get in there quick! You won't forget it!
