This place felt like a jackpot, it is really central and you are staying at a really nice hotel for a fraction of the price. The pool is beautiful, the staff are professional, and the place is neat.
Having said that, it is a bit odd to feel like you are in a hostel. So, if you are not comfortable with the idea that someone could be staying in the same room as you it might be worth finding somewhere else (no one else ever came in while we were staying there, but worth being aware of). There are lockers to put any belongings into which was very helpful and the staff will hold your luggage past the checkout time, which saved us for check in time into our next Airbnb.
Lastly I last minute added a friend onto my stay and they accommodated, but the price did double which I was not necessarily expecting.
Overall, great find, I will be recommending it to any other friends traveling by themselves through Vienna.
