Ross's apartment is a great base for exploring Edinburgh and is conveniently located on a frequent and punctual bus route, however if you're feeling energetic and the weather isn't inclement, it's a nice brisk 30-minute walk into town (or 45-minute leisurely stroll).
There are two major supermarkets located nearby, and a range of shops and cafes not too far off. If you're a fan of Hibernian FC, this is definitely the place to stay as the stadium is a few minutes walk away. If you aren't, the flat is far enough away not to matter!
The flat itself was clean and well-appointed, with an accumulation of basics in the kitchen and bathroom, the check-in process a doddle, and we thoroughly enjoyed our time in Edinburgh.
There was a power cut to a large part of Edinburgh late on the second night we were there, and we didn't discover until morning that the electric water pump had tripped and we had no water, but Ross replied within minutes of being advised and the matter was sorted out by the time we returned that evening. We were still thankfully able to cook bacon and eggs before heading out!
Overall a great few nights and I wish we could have stayed a bit longer.
