The apartment is just wonderful; beautifully decorated, heated bathroom floor, a small radio in the bathroom which comes on when the lights go on, a washer and dryer, everything was just perfect! The location was so convenient, we took S7 from the airport to Rennweg Bhf, then tram 71 for 1 stop to Unteres Belvedere, apartment was a few mins walk from the stop. From Rennweg Bhf, the S1,2 or 3 took us to Wien Hbf train station. We used a lot of tram 71 and U4 which is also nearby. Thank you!
