We visited in November and the apartment was warm, clean and spacious, although it didn’t quite match photos shown on the site e.g. different sofa and coffee table and lack of a lamp in the lounge made it difficult to read at night. It is however well located near Stadtpark for transport links, so a good base for exploring Vienna.
The pizzeria next door was fantastic and having a Spar just around the corner for small bits of grocery shopping was very useful and not expensive.
The CAT (fast train) from the airport was not running (and won’t be for the next year) but the OBB (stopping)train was easy to use and only just over 4 euros a person to Wein Mitte/Landstraße near the centre of Vienna and a 10-15 minute walk, or one underground stop, to the apartment.
Christmas markets had started just before we arrived and they made the atmosphere absolutely brilliant from sunset. The biggest was Rathausplatz and well worth a visit.
