We stayed at Claus’s place for four nights. To put in succinctly, it was PERFECT. Communication was excellent, check in easy, location was literally right in the middle of everything (yet the apartment was nice and quiet!), and the apartment itself was better than we had expected. I say that because the apartment is nicer than the photos show. All amenities are provided, it’s warm, the beds are comfortable, shower great, as I said above, it’s quiet, and the location is perfect. I would stay here again for sure, and would highly recommend it to anyone who is coming to explore Vienna for a few days or more. Thank you Claus and Joahanna!!
