We had a lovely time at Sue's and Grant's apartment. The view from the living room's window seat was especially memorable, and we enjoyed seeing the sun rising behind Arthur's Seat every morning. It's only a short walk to the start of the trail, which leads up to the top of Edinburgh's local mountain (approx. 10min) and not much longer to Holyrood Palace, the lower end of the Royal Mile (approx. 15min). We were able to reach every destination on foot (that's why I can't say anything about public transportation). You can also get to the nearest supermarket/Sainsburys on foot (approx. 10 min), which offers many things. Sue and Grant always answered our questions and problems, which was also a big plus. We had to get used to the heating regulation, but once we got it, it worked perfectly well. Would totally recommend this apartment.
