Daniels room is to be found in an abolutely charming, old Viennese Jugendstil building! The location can not be better, the historical centre of Vienna is within walking distance. And for those who do not enjoy walking: the metro station is only 5 min away! There are plenty of cafes, restaurants and shops around. We truly enjoyed staying in such an excellent location, which definetly made up for some sort of shared-flat concept of cleanliness :-)
We did not meet Daniel himself, but his flat mate was easy to contact and received us friendly even tough we reached Vienna due to traffic jams 20 minutes later than expected. As other guests wrote, there is no private space to put your belongings (cloths etc) in Daniels room, we just lived out of the suitcase which was not a problem for us, staying for three nights only.
To sum up: I recommend Daniels place if you want to explore Vienna from an perfectly
located, authentic students flat with very good value for money!
