I shared this apartment with two colleagues during 6 days for a conference at TU Vienna, and we couldn't have been more satisfied. Alexander prepared a useful welcome guide, and the apartment was clean when we arrived. The location is interesting, close to the university, to metro stations and to the Ringstrasse. Although we didn't have time to visit the city, Alexander proposed many books and guides to plan some visits. It is a nice alternative to expansive hotels in the neighborhood.
