Garry's place was a good spot to crash for the first half of our Edinburgh trip! The neighborhood is quiet and peaceful, and a quick Uber/bus ride into the main city. A 5-minute walk to the Water of Leith walking and biking trail as well, which I recommend. Check-in and check-out is very easy with this particular building.
Only two notes. First, the description says that there's breakfast foods in the unit, but we only found some tea and instant coffee. Second, for U.S. visitors, the toilet has less flushing power than we're used to. That's more of a general thing, though, rather than a specific thing to the place. (There is also not a plunger, which made me scratch my head a little.) But otherwise, definitely a good stop for an Edinburgh trip, especially for 1-2 people or if you want to see other areas of the city besides the centrally located Royal Mile!
