The flat has the most amazing location that we, as tourists, could ever have hoped for. On the entrance doorstep was the Fringe festival, and every single place we visited was approx 12 mins in either direction. No need to use public transport and you find yourself in the hub where you meet new people.
The flat itself was absolutely dreamy with amazing views of sunrises and sunsets over the architecture and sea of Edinburgh. Could not get enough of the window seats as well. We also had bubble baths and enjoyed the kitchen for breakfasts before heading out.
I would recommend visiting all the nearby cafes in Edinburgh, not more than ten minutes away by foot: press coffee, cult espresso, filament, the holy garage, brew lab, artisan roast, and fortitude. The flat is also near Arthur's seat if you want less city and even more views.
Jo was a lovely host who gave us all the info we needed and more to have a lovely time in Edinburgh and the flat. The no-key system was also brilliant. For a short trip, this high quality flat and amazing location is absolutely perfect.
