Close to Wien Hauptbahnhof and local supermarkets, restaurants easy to move around, didn’t felt unsafe at all, mattress is good, the place was clean, they got TV and air conditioning including Netflix.
However the shower had no water pressure, this bothered me a lot, I found the toilet to be very small and the sink so small too, the curtain was broken and this was reflecting the sun in the morning, forcing us to wake up earlier than needed.
Would I stay again ? No, I’d be probably be looking for something more spacious and with good water pressure.
