It was super comfortable. The apartment is located near to all the attraction. It’s very quiet so you can really have a good sleep. The space was way spacious than I thought. A group of 5 people can dance in there as it’s very spacious. Klaus was very friendly and gave me a lot of advise as to what and where to go. I enjoyed the puncsh :). The kitchen is full of free food and coffee so you don’t have to worry about your breakfast. I had an amazing stay. I hope to stay here again next time I visit Vienna :) Thanks Klaus!
