Michael's place was perfect during my stay in Vienna for 5 nights. The location is very good, close to metro and also within walking distance to all the major sights in the city center. The room is cozy and having the shower and sink in the room was a great plus.
Michael was also a very good host with great communication, very clear and quick responses. We didn't meet but he was still very present from the beginning to the end.
I recommend and whenever i come back to Vienna i know where to stay.
