The positives:
Amazing location
Very comfortable beds.
Check-in went smoothly.
The negatives:
Be aware that, even with shades drawn in the day and windows open at night, it gets hot in the attic penthouse. The agency did not know if there were fans in the apartment (we looked but couldn't find any) and they might have brought some over, but it would be nice to have a few fans in the apartment.
Ant infestation -- They were there when we arrived and we were careful to not leave any food laying around. Who hasn't had ants in their house at some point, though, right?Still, it's not pleasant.
But it was the toilet paper that really disappointed us. The apartment is sparsely decorated and offers few amenities, yet the listing clearly states that it supplies the necessities, including toilet paper. Who thinks to check for a spare roll before actually needing it? One partially used roll in each bathroom, six people and two days later (Sunday) we discover there is not a single roll of toilet paper in the apartment. The host said he couldn't help us. The rare grocery store that we could find open literally had the paper product section roped off because, we soon learned, Austria forbids the sale of toilet paper on a Sunday. We had to resort to stealing it out of the bathrooms of cafés!
All because our expensive penthouse Airbnb in Vienna couldn’t be bothered to provide a few spare rolls of toilet paper!
So, sadly, we cannot recommend staying in this apartment. For the price, it's not worth it-- unless you happen to like sparsely decorated, hot, ant-infested, toilet paperless, penthouses.
