Kate's apartment is fantastic: modern, spacious and clean. Everything has been thought of, extra blankets, towels and a hairdryer is available to use. It's very centrally located, about a 15 minute walk to the centre of Edinburgh. Holyrood Palace and the Parliament building are only around the corner.
The bedroom has 2 single twin beds which are very comfortable and the wardrobe is huge so you can easily put away your things. If you're quite sensitive to the light I would bring a sleeping mask with you as it can get quite sunny.
Can't wait to return!
