Anna's flat is very conveniently located and has everything you need and nothing you (probably) don't. It was really helpful, for example, to have some working scissors to cut tags off things. The apartment is very close to a Sainsbury supermarket and there's even a cat cafe a few doors down if you need some feline company.
Anna herself is very welcoming and helpful. Her coffee recommendations (especially Kilimanjaro) are excellent. Staying with Anna was a great experience and if I'm in Edinburgh again I'll be back if I can.
