Located next to the U4 and a five minute walk from Naschmarkt, a big local market. About 45 minutes from the airport by 2 trains. Shower and sink is located in the room and the toilet is shared amongst the other guests on the floor. The downside is that I saw only 1 toilet and 6-7 rooms but as long as multiple people don't have to use the toilet at the same time you should be fine. The check in was different as you are given a code the day before arriving and punch in the code to get into the building, the apartment, and then your room (two separate codes, one for the front door, and another for the apartment and your room). Overall a good stay.
