We were a family of two and stayed at Andreas for a week. He was good in communication and the place was perfect for us. Apartment is located within a 5 walking distance from the major train stations Stephansplatz and Schwedenplatz. There are two supermarkets "Spar" and "Merkur" within a 2 minute walking distance. Highly recommend for a family of upto 2/3 people. There is a direct bus from the airport that brings to the city center "Vienna Airport Lines Bus Stop on google maps" which is 5mins walking from the apartment.
