Andreas and his representative maintain a superb hot-line communication.
Aparthotel Bianca was transformed from an apartment house in the Favoriten district of Wien. It is a 15-min walk to the metro line U1 Reumannplatz, from where it takes a net ~10 min ride to Stephansplatz. There are some tram lines in less walking distance. Download the WienMobil app to buy city transport tickets of all sorts.
You have to pay for car parking on the streets during weekdays until 22:00. We solved the parking for €6 per day at APCOA open-air parking, 1100 Wien, Raxstraße 38, which is 15-min walk from the Apartment. Use apcoa.at or parken.at to find more options.
Apartment 502 was like a superb hotel room with a fully equipped kitchen (really everything was available like at home, among others an electric cooking hob, and a coffee machine with capsules). Perfect bed for two, clean sheets and towels, big bathroom with a good hair drier.
In Viennese terms, the place is a good value for money.
