the appartment was very clean and spacious, graet for us - a family with 3 kids (although - only one shower..). the host answered immediately to any question.
still, the fact we had to climb 3 floors with no lift was a surprise.
also, the appartment is in a nice area, but at least 20-25 minutes walk from the center (MuseumsQuartier).
in the appartment: big comfortable beds, very few glasses and cutlery in the kitchen, no coffee cpsules for the coffee machine.
we did use the washing machine, which was a nice addition.
