We spent two nights at Kadira's place in August. It's an old apartment block that is well located for all that central Edinburgh has to offer (<5 min walk) but quite tired on the inside as you might expect for such an old building. The entrance is a dingy stone stairwell via two flights of stairs.
Kadira has done a good job furnishing and looking after the apartment and she was helpful and very easy to communicate with. Contrary to the listing, it's worth noting that this apartment does NOT have parking available - all the surrounding streest are double red. You'll need to use the local private car parks if you are arriving by car.
The apartment smells of smoke - it's reasonably clean, but could do with some extra attention (eg. cleaning of/removal of throws/scatter cushions) in the light of COVID-19.
