I stayed at Ben's place for 5 days, and it was really fantastic!Apartment was clean and rather spacious. The building is quite nice and modern, big plus that there was an elevator. Sightseeing was not my aim during visiting Vienna, but still the place was close to Mariahilfestrasse or any subway line.Ben was very pleasant and helpful, he met me and explained everything.So I definitely recommend to stay at Ben's!
