This is a nice and cosy apartment and close to basically everything in Vienna. A suggestion would be that the host mentions clearly that the check-in is by 5 00 pm. At times (like in our case and the only minor issue we faced) it happens that one reaches the city early and cannot check in till 5 00pm. However Markus did help us with storing our luggage. Overall it was a good experience and we highly recommend the apartment.
