Great location and great host!
Perfectly connected with the rest of the city by the metro.
Parking is a little bit hard. There is a underground parking garage in the near but it's waaay to expensive (80e for 2 days). There are options to login to an app for cheaper parking but it's very complicated and not supported for all countries. So it's better to park in some of the "Park and Ride" parking garages at the beginnings and ends of the Metro stations that charges you 3-5 euros per day which is really affordable. If you don't come by car then it will be the perfect stay in Vienna.
Also the Wifi could be a little bit better but you don't come to vacation for the Wifi ;)
Host is very helpful and responses in a short period of time (mostly 15-ish minutes).
