It's really easy to get to the apartment from the airport, a 30 minute tram ride at a cost of £8 return. The tram stops at St. Andrew's Place which is just about a 5 minute walk to the apartment ( but down a very steep hill). Abercrombie Place is very quiet and yet extremely convenient for the attractions of central Edinburgh.
The apartment itself is nicely furnished, well maintained, comfortable and spotlessly clean, Veronique seems to have thought of everything.
I would have no hesitation in recommending a stay here.
