Though we did have a wee bit of trouble finding the flat, as Google Maps was confused by the address, check in was super simple. We were excited to find that the view really was a legitimate front row seat to Edinburgh castle. For us, it was within walking distance to nearly anything you'd want to do in Edinburgh, including The Royal Mile, the Grassmarket area, Princes Street, Waverly Station and Dean Village. You do get a bit of noise from the street up to the bedroom, which is to be expected from such a central location, so a white noise app on your phone does come in handy!
Also during the time of our stay (Oct 2018), there was construction going on outside of the building so you will get a bit of that noise during the day -- not at all the fault of these wonderful hosts, but good to note!
