Need some info on some hotels in Vienna

[Pkrbt]

Sry if I'm writing this in english but I figured I would get better feedback here rather than in the B&M forum.

I'm planning to go to Wien tomorow for a week to play live at Concord casino and would like to book a hotel. And this is what I found for 3 (will be there with 2 other m8s).

ActiLingua Apartment Hotel 3 stars

Schneidergasse 7, 1110 Vienna
At around 800e for 8 nights for 3 people.

Anyone know any better deal or should I book this one?
