Gerhard and Nicole's apartment is every bit as beautiful and unique in person as in the pictures. The hosts are very communicative and accommodating; we arrived early in the day and they let us store our bags in the apartment prior to our check in time so we could go out exploring. The location is great - the neighborhood has many interesting shops and restaurants nearby (be sure to try Ulrich cafe!), and only a 10 - 15 minute walk or so before you reach the Ringstrasse and the beautiful city center. We stayed for 4 nights and would gladly do it again!
