Mario's place was much better than expected. Check-in was smooth, stay was comfortable and amenities were perfect. One thing that stood out during our stay was the location , Mario's place is in the center of everything. Train, tram, bus or Subway - everything was 5-10 min away. The Vienna airport lines bus station was also within walking distance. Will highly recommend his place to anyone planning to visit Vienna esp. if you're going to use public transport for commuting.
