This apartment was in the perfect location! Great views of the castle and right on Grassmarket. Walking distance to everything, while also giving a feeling of being out of the main hustle and bustle. Just a couple warnings, there are many stairs, but as many people have mentioned, I wouldn't recommend Edinburgh if you can't do stairs or hills. Also, I don't recommend having a car with you while there. If you do, definitely park it on the outskirts of town where there isn't paid street parking and then take the bus to the apartment. Street parking is £3/hr between 8:30 am and 6:30 pm, and the nearest paid parking garage is £27/day. The apartment itself is exactly as advertised and I thoroughly enjoyed my visit there.
