Great location with a beautiful view! A very handy local grocery store a couple of minutes walk. My family appreciated the elevator. Place was very spacious and kitchen, dining area and living room area is very open which we loved.
Walking distance to so many things that it would fill the rest of this post. Something I recommend is the Edinburgh Bus Tour, you can pay for it online and jump on the bus right outside the flat at Dynamic Earth (1 minute walk).
Great 2 week stay!
