Great place with a very nice romantic courtyard, away from the noise of the main street. Great location, with the Mariahilfer shopping street very close, along with Neubaugasse subway station, and central Vienna maybe a kilometer away. Very nice communication with the owner, no-contact COVID safe check-in and check-out. Some small goodies were provided as well after check in (waffles, small sparkling wine and FFP2 masks)!
Only real downside is that the laundry machine/washer is a laundromat close by, if you want to wash your clothes.
