Great apartment only in Edinburgh's city center. It's super convenient if you're traveling on the Airlink (airport bus) and don't want to lug all your bags around the city. You can get off at Waverley Bridge and it's only a few minutes up Cockburn St from there.
The apartment is a 3rd floor walk-up, keep it in mind if you're traveling with heavy luggage.
The apartment itself is warm and cozy and has nice views of Princes St and the Balmoral hotel. We stayed there with a baby and had a great time.
