My wife and I stayed in this apartment for two and a half months visiting family, and it was a really wonderful and comfortable place to call a temporary home: The layout works really well for a longer stay for two people - it's compact, but you get a bit of space for yourself. The kitchen is pretty amazing (induction cooktop, a decent small dishwasher, well-sized compact fridge & freezer) and comes with a bunch of storage space in case you really do want to cook for two: As we were there during the November 2021 lockdown, we were really happy to have it.
If you can go out, the apartment is in one of Vienna's hippest districts and there's some excellent dining options just around the corner.
Christiana, the host, was super friendly and regularly checked in with us to offer cleaning services: That was much appreciated, and we were really happy with the result, too.
Overall, we really enjoyed our stay and can recommend this place!
