Everything was great. We were received with a warm welcome by Siegfried. The place was absolutely clean and nicely furnished. The location is perfect. The rooftop is minimal, but nice to hang out. There is everything you need in the kitchen (salt, oil, tea, etc.). The wifi is not so strong. Might not be enough, if you want to do some serious work, but for vacation it was perfectly enough for us. Siegfried helped us, whenever we needed, and we could leave our luggages until we wanted. Great place to stay in Vienna.
