I stayed here for 4 nights with my wife and Glenn endured there was no stress with the accommodation. He was proactive with communication and check-in, with everything really smooth and easy. The apartment is an easy 25 minute walk to the centre, or about 40 minutes to the top of Arthur's Seat. The immediate area has a busy-ish road with some noise at night but nothing you wouldn't expect in a city suburb. We slept really well in the comfortable bed, and there's a nice lounge area for relaxing. No TV though, in case that's your thing. Kitchen has everything you'd need (oven, microwave, utensils, crockery) and a table for 6.
I'd definitely recommend staying here.
