Three of us stayed in Elke's charming little apartment for two nights in April. It is exactly as described and the photos are accurate. Very clean, well-equipped, warm, and in a quiet neighbourhood just 5 mins from Schwedenplatz metro (which we only used once to get to Schonbrunn castle further out), otherwise most of the major sights in the city were within 10-20 mins walking distance. Supermarkets are very close by. We met Elke as she checked us in and took us up to her apartment (there is a tiny lift/elevator). Elke is super nice and responsive and gave us tips about an Easter market happening at the castle (which we checked out on our second day). I would definitely recommend Elke's place if you want to experience living like a local in a quaint little apartment just slightly away from the hustle and bustle.
