The view up the Royal Mile from the apartment window. The three church style buildings are:
Nearest: Tron Kirk. Middle: The High Kirk of St Giles. Furthest: Tolbooth Kirk
Edinburgh Castle is at the top of the road just beyond Tolbooth Kirk.
Tip: The souvenir shops can be cheaper if you walk down the Royal Mile from the apartment away from the main tourist area. You can have a look at the Palace of Holyroodhouse while you're there. It might even be open to the public!
