Great location, very close proximity to shops, Princess Street, Waverley Station, Edinburgh Castle. Charming neighbourhood, so I really recommend the place for its location. The apartment is below street level, so that was an interesting first experience for me. I quite enjoyed it. It might be that the locals are not bothered by the cold in the city in general and it's reflected in their living spaces as well, so I was a bit worried about the coldness in the apartment overall. The electric heating was not enough to keep us warm, but it was alright.
Overall, a great experience and Jonathan has been really responsive and helpful.
