This apartment was very well maintained, modern and comfortable. There was plenty of space to move around and the bathroom and bedroom were very nice. The location of the apartment was in a typical neighborhood and was safe and quiet. It was about a 15-20 minute walk to the center of Vienna attractions. However, the metro was just a few blocks away that would take you into the center in minutes. Communication with Guido and Maria were all good. However, please note that this is a company with staff who are assigned to meet you upon arrival. If you are delayed or late as we were due to a train incident, they have other obligations, so rescheduling could be an issue. However, in our instance Maria arranged for us to self check in so all went well. A very nice place at a fair cost .
