If you're visting the area like I was then it's a good location for walking to the sights, there's bus stops close by if you'd prefer.
Once you're inside the space itself is fairly shabby and outdated but not uncomfortable. The kitchen is equipped with a fridge, oven, toaster, and electric kettle. There was no cooking oil left in the bottle so I had to buy some more (didn't want to travel with a bottle of oil so I left it behind), there's plenty of salt but no pepper. All the "sharp" knives are incredibly blunt, and the frying pan is warped so it doesn't really work. The kettle's spout isn't attached on one side so pour over the sink otherwise boiling water will piss out the side. The gas/heating system is incredibly loud and can be heard in every room. The bathroom needs some serious resealing, nothing seems watertight. The bed was fairly comfortable, and the bedroom well equiped.
Overall, I enjoyed my stay in Edinburgh and appreciated having a roof over my head.
