Yvonne & Gurvinder informed us about all needed information at the right time. The check-in and checkout process was no hassle even we did not meet the hosts in person. It worked like a well-oiled machine as they do offer several apartments in Vienna on the airbnb platform.
Noteworthy are the clean and comfy beds. The metro line 1 reaches a lot of tourist destinations without changing trains, so it does not matter not be in city center of Vienna.
