My advice . . .if you want to enjoy your time in Vienna, find another place to stay.
Pros:
This place is very close to many of the tourist attractions, shopping and dining.
The living room is spacious and comfortable to relax in.
The building has an elevator.
Cons:
The host is rude, inflexible and will berate you if you don't show up at the EXACT time you provide to him. He doesn't believe the public transportation in Vienna is ever late. We had two delayed trains during our time in Vienna. He tried to charge us extra for arriving 10 minutes late. 10 minutes. I told him we'd be there between 4:30 and 4:40, we arrived at 4:50 due to the late train. He was rude to me on the phone, hung up on me and then demanded via message that we pay 15EUR to the person who let us into the apartment.
On display in the living room of the apartment were 15 books on Hitler, Goebbels and Nazi propaganda. ALL pro-Hitler and focused on the height of his rein, praising him. This made us very uncomfortable and is inappropriate to have on display in a rental property. I immediately started looking for another AirBnB or hotel in the area, but nothing else was available.
The hot water heater is set up so you only get about 5 minutes of hot water to shower in before it switches to cold. You then have to wait 30-45 minutes for the hot water to be ready again before another person can shower. We had a group of 4 and this was completely ridiculous to deal with. While there are two bedrooms to sleep 4 people, the amount of hot water does not accomodate 4 people.
The street at the front of the apartment is fairly busy so there is a lot of traffic and pedestrian noise throughout the day and night. At the back of the apartment is a courtyard where the garbage dumpsters are stored. There was also a lot of noise coming from the courtyard, including very early garbage pick-up.
