I couldn't meet Gerhard&Nicole in person for check in nor check out, but direction was very clear, and responded quickly with our questions. Looks even better than the pictures. It was much better than I expected! Especially, the location was PERFECT! There were lots of nice cafe, restaurant, and shops near by. Very safe to walk around at anytime, including at night. If I visit Vienna again, I would love to come back and stay at Gerhard&Nicole's place again. Don't hesitate, it really is a great place to stay! :)
