I arrived in Vienna, taxi from airport, only to find the number given for address was zip, not house number. I had no internet to make contact, so stayed one night at hotel and sent message about address. And next morning it was provided. Otherwise, the apartment stay was wonderful. Beautiful, clean, and maybe a 10 minute walk to SCHONBRUNN. Many food stores minutes away. My only suggestion is make sure you get a) full address, number and street and b) WIFI system and password….before arriving.
