Caroline's place is perfect if you want easy walking distance to old town. I don't think you can get much closer to the royal mile. It is in the middle of the bar area though so be prepared for noise and some smells. The home has all the basics but was missing the extras you become used to when staying in Air BnBs. We had to go buy paper towels and coffee and other minor items for our stay. Caroline was very professional and gave us all information ahead of time, we never met or had any interaction with her though which would've been nice. Overall we had a great stay and found this to be a perfect spot to explore Edinburgh.
