Pascal and his family are really nice and reliable. My boyfriend and I stayed in Wien for four days and we really enjoyed our time there.
The position is perfect: the metro is 1 minute walking distance, but we chose to move by feet in order to see the architecture of the city. Stephansdom is a 15 minutes walk away. The district is very nice, the house is nearby the museumsquartier and the kunsthistorisches museum.
Everything in our experience was cool. The room was clean and elegant, the towels provided were big and soft and the bed was comfortable. We highly recommend it!
