We stayed at this apartment for one week in Feb 2019, as my husband was at a conference in the Messe Wien conference centre... and we couldn't have gotten much closer to the venue! The conference centre, Messe Prater underground, Aldi (called Hoper in German) and even a McDonalds are all 5 mins walk from apartment. There is also a little, very hidden, Italian restaurant which serves humongous pizzas (L'Osteria!) The location is slightly outside the city centre so alot quieter but easily accessible on public transport. Apartment is very modern and clean, however it is up 58 stairs so may not be suitable for those with mobility issues. The windows face into a dark courtyard so no real view but this didn't affect our stay. The bed is king-size but is actually 2 single beds pushed together. The mattresses are very soft which wasn't quite to our taste. Other amenities included a security safe, Netflix and hand soap. We would definitely recommend this apartment and felt it was good value for money.
