I stayed for a week at Vincent's place while in Vienna for a workshop in the VIC.
Vincent's place is around a 7 minutes walk from Vorgartenstrasse station. It is nice and clean, spacious and has all the amenities you need for a short term stay in Vienna.
You'll get a room with a queen size bed, a table to do work on, a cabinet for keeping clothes as well as access to a wonderful balcony.
The apartment has 2 toilets and 3 shower rooms and is equipped with a kitchen (with 2 fridges!), a living room and another common balcony.
There are other occupants in the 5 other rooms so you should have no issues getting help if you have any problems.
Luca was helping Vincent with the hosting during my stay and both of them were really helpful and ready to assist with any queries you may have.
Overall, this AirBnB rocks! 10/10
PS: if you find that walking 7 minutes from the station to the apartment is taking too much time or if the weather is too hot, you may want to rent a Citybike to get to the apartment, get changed and/or washup and return the bike within an hour. Alternatively, you may choose to take a bus from about 2 blocks away.
