Astrid was not there the weekend I was in Vienna, but left arrangements for me to collect the key and get to the apartment. The apartment was very nice and spacious. The room was comfortable and there was left ample material on what to do and see around Vienna. From the apartment, it is only a 6-7 minute walk to the Staatsoper and from there, you are really at the centre hub of Vienna. It is serviced well by Metro stations and has lots of places to eat, drink and supermarkets within minute of leaving the apartment
