Dali's apartment has a great location and it is easy to reach the centre of Vienna even on foot. Both Dali and her husband are both nice and polite people.
However, I have to say that this room should not be advertised for 'up to four people.' The infographics on Airbnb (not the photos) clearly show a double bed and two matrasses. We were surprised to find a barely 1.5 bed and one matress on the floor. Luckily, we were just three in the end, I cannot imagine staying if we were four (as originally planned).
Also, there is 0 storage room, not even one shelf, so we had all our belongings on the floor around where we slept, which gets quite messy. Dali was nice enough to offer one of us sleeping in the walk-through living room, however, we decided not to disturb her family's privacy more than necessary. To be absolutely honest, I can recommend this accomodation to a traveling individual or an easy going couple, but different groups cannot be comfortable in this little room.
