This apartment has a perfect location for a weekend in Edinburgh for a couple. Close to everything, and you can walk to nearly all the sights in the town.
Even it is located right next to the Grassmarket it is not noisy.
Duncan was a perfect host, and he even let us keep our luggage in the apartment on chech-out day until late afternoon, as we had an late flight out of Edinburgh.
I will recommend this apartment to all fellow travelers.
