Gregor's house is a nice and lively students house with a lot of lovely hosts that are very friendly and happy to help. Gregor's room is amazing and it is the type of room I would have liked to had when I was a student. There are some narrow spaces because of the shared nature of the house, but that comes with the territory, if you can cope with itthen you are set for the perfect place to stay while you explore Vienna.
Also, wicked stickers all around. I could have took pictures of nearly all of them ;)
