Caroline was unable to meet us, but her emissary Paul was great with contact and greeting us when we arrived. They offer a great little neighborhood cheat sheet as well as some stocking-the-kitchen options -- we went with the lovely which allowed us to have a nice beer and cheese happy hour when we arrived. The apartment itself is gorgeous -- the pictures don't lie! It's located just outside of the Ringstrasse so it's a quieter neighborhood. Which means that if you're out late you may need to catch that Night Bus, but it's also very relaxing and gives you time to recuperate. I would absolutely stay here again!
