Stylish and spacious studio flat. Flats are roomier than you might think from the pictures, but are otherwise identical - I was also staying in their smallest one. Shower is great - powerful and hot! The price is extremely good, with the only real downside being the location, which is a little far out, but the Hetzendorf station a 5 minute walk away will get you to the centre quickly (and is a better option than the tram station outside the front door).
The TV doesn’t have Netflix or allow for it to be used on browser, which is a bit aggravating, but this is a minor niggle.
Note that if you are 6 feet tall or taller you will need to stoop a little for the bedroom mezzanine, but that’s not a big problem as there’s nothing to do up there except sleep.
All in all would strongly recommend, particularly to anyone on a budget
