We stayed here for two nights while visiting friends and would recommend it. It is close to both the S-Bahn and the U-Bahn, so getting there from the main train station is easy (about 20 minutes). It is in a cool neighborhood - down the street is a nice pizza place (Randale) and the Prater and the Augarten are both very, very close. It is about 10 minutes from the center (St. Stephans Platz) and there are a few grocery stores within walking distance. The apartment is easy to find and check-in/out and general communication with Illia was easy. It is not a cozy space, but it has everything a visitor needs and is really good value for the money.
