Christian's apartment was a very nice surprise for us, finding it very clean, well and enough equipped, with modern design. The location is 2 min walk to 37 and 38 tram station that connect you to the city center in 10 min (4 stops). Many shops around the apartment building (Spar, Bipa, Favas Spanish groceries, fruits&vegs shop). We really recommend it for a city break or longer stay in Vienna.
