Very nice appartement, well located, at a walking distance of everything (castle, botanic garden, shopping...)
Confortable bed (but not a king size actually), nice bathroom, Netflix..
If you like to spend time at home and chill, the sofa is probably not the most comfortable.
Located on the basement floor, there is not very much light.
One detail that bothered me but I’m sure it will be taken into account for the next guests:
I always find it nice when I rent a place to find a plug adapter, a hairdryer, coffee, sugar, salt, oil and vinegar, and maybe some kitchen cleaning paper and napkins.
I would definitely recommend the appartement to anyone who wants to go for a short stay in Edinburgh (and by the way Sonia and Chris react immediately if you have a question or a problem)
