The Gordons were very friendly and gracious hosts, who were quick to respond to our questions and needs.
The apartment was very clean and well-stocked with necessities and extras. The space itself was airy due to the split-level loft design and is flooded by natural light during the day. The location is superb- just half a block off the Royal Mile and a hop and a skip away from the Waverly train station and the Edinburgh Airport Express bus stop. The only drawback for me is the lack of internet in the apartment, though there are numerous spots offering free WiFi just outside the building.
Overall, we had a very comfortable and cozy stay at the Gordon apartment and would happily recommend it to anyone visiting Edinburgh.
