It's a really lovely apartment, with some good views across the city. Two good size bedrooms, huge bathroom and a sitting room/kitchen that has everything you need.
It is a 15 minute walk to all that Old Town has to offer. I won't give any tips for around there but if you stay here, make sure to make time to go up Calton Hill. It takes about ten minutes from leaving the apartment to be at the top of the hill and the views are unbeatable, truly stunning. You get the castle, Arthur's seat, old town, new town and the beautiful mountains surrounding it.
We had food and a selection of beautiful deep fried Mars bars from the chipper below. Please try one, it'll change your life.
I would recommend walking the 5-6 minutes to the Joker and Thief pub, super paid back bar with a serious selection of beer. Does pizza too. Seemed to have a good crowd of locals in too.
Jeremiah's taproom is another great bar for a wide selection of good beer and the food was probably the best we had in Edinburgh. The haggis was deadly. Also watched some of the six nations rugby on their projector screen there.
