As soon as we arrived, we checked in at the reception. We went up to the 19th floor - beautiful view! In the apartment we had everything that we needed, and we found everything that was stated in the listing's description. The apartment was exceptionally clean and very very comfortable. Everything was working fine. From where the apartment was situated, we could easily and quickly reach the city center via metro. When we returned back to the apartment, it was no problem to enter the house and our apartment. The reception is open 24/7. We could also always ask the receptionist or the host any question we wanted. They were always very helpful, and the host answered very quickly via the Airbnb-app. All in all we really enjoyed the stay in Vienna and we will always look for this specific apartment first, next time we go there. 5 stars out of 5!
