We had a good stay in Vienna. With respect to the apartment everything was great. It was clean, location was excellent, check-in was smooth etc. We can see that Karl and Lisa had really tried their best to be an excellent host. I really liked their attention to detail and whenever we had queries they were very quick to respond. The only problem we faced was there was some problem with hot water in shower which was a little bit on inconvenience. Otherwise we had an excellent stay and we highly recommend it.
