We stayed in this apartment for three nights and had booked it under the assumption that it has air conditioning because it is listed as so under the amenities. However, there is no air conditioning and they only have one small fan for guests to keep themselves cool from the summer heat. This apartment is rather far from anything you'll want to see in Vienna as well.
The shower is just open in the hall with just a shower curtain for privacy. One of the smallest showers I have ever been in. If you're trying to shave your legs at this apartment-- just forget about it. There's absolutely no room.
