I had a great five day solo stay at Ella's place. It is equipped with everything you might need and the bed is comfy. The apartment is so centrally located that I ended up doing most of my sightseeing by foot, there are a few nice restaurants, bars and cafés right in the vicinity. The construction site outside the house was a bit noisy at times, but it was not a problem since I was out during the day and if you sleep with earplugs, you won't even be woken up early when works starts in the morning. Communication with Ella was always swift and uncomplicated, we even met and had a nice little chat with some extra Vienna insider tips being given. Would recommend and of course stay again.
