By far the worst Airbnb experience we ever had.
On our second day in Vienna, the intercom to the building got broken. Since we did not have a key to the main door, each and every time we wanted to get to our apartment, we either had to try and convince one of the neighbours to come down and let us in or wait for someone to come in/out of the building so that we can get in. Apart from that, the host did not show much interest in trying to solve the issue as we had to text and call plenty of times only to get the same reply saying that they were trying to reach the landlord. Not only this, but they also lied to us saying that the building management "turned off" the intercom during the holidays. We learned a few days later that the it was actually broken.
Apart from all of these, we got the chance to speak to some of the neighbours during our attempts to get in the building. They were saying that they're fed up with that apartment being an illegal airbnb. Not sure if this is true but the neighbours are definitely not enjoying the guests in that apartment.
It's worth mentioning that the apartment has a really great location and it's within walking distance to a ton of attractions. It was also decently clean, but no cleaning service was provided during our stay.
