The apartment is in a great location to visit Wien. You have the Westbahn station nearby and the main road is full of supermarket and food shops of all kind. Really easy to arrive there.
The building is ok, checkin too. You will feel safe and no noise at all (I was working home during the lockdown). Place is good for 1 or 2 persons.
Large TV with german channels wasn't a problem to me, I enjoyed the background (bring an HDMI cable if you want more). The bed is very comfortable, like bathroom, and the heat was perfect. Kitchen was equipped enough and the washing machine was ok.
Boris is a good host, I did not have any problems or request. Definitely recommend staying in this apartment, you won't regret it!
