I would definitely return to Klara's flat if visiting Edinburgh again. Klara is communicative and her flat is as advertised. The kitchen in particular is very well equipped, excellent for cooking meals, and there are thoughtful provisions throughout the flat, including hand sanitiser, a sofa throw, and luxury towels.
As other reviewers have noted, there are noisy neighbours upstairs who can be heard from the bedroom, so I would recommend bringing earplugs.
