This place is great. A real highlight of our trip. Stunning views up to the castle and out onto Grassmarket. Very comfortable and roomy place. Lots of food, bar, and pub action (and a great Saturday Street Market) just outside the door on Grassmarket but a thoughtfully placed double paned window in the bedroom keeps it quiet in the apartment. Newer fixtures and washer make this an excellent home base. A short walk up the hill to the Castle and Royal Mile sites. Maureen's communication and instructions were timely and detailed, very useful. Only potential downside for some folks may be the 3 flights of stairs but we did fine and we are well into our 60's. We were glad we got an Uber from the Princes Street tram stop coming in from the airport with luggage. The distance to the apartment is not great but there is a fair amount of up and down hill involved. Once the luggage is dumped, the sights are easily gotten to by walking or jumping on the hop-on / hop off bus. Tip: The Beehive Inn a few steps up Grassmarket has a very nice beer garden / patio out back for a drink or lunch on a sunny afternoon.
