We stayed here for a month (June). This is a fun place with an open concept design (the only door is to the WC ). Comfortable loft bed, well equipped kitchen, super clean. Only minutes away from Mariahilfestrasse (happening shopping and restaurant street) near two Ubahn stops and the 49 tramm, yet overlooks a quiet, flower filled courtyard. The Metro/subway in Vienna is amazing, so you are only minutes away from the State Opera House, museums, Musikverein, Stephansplatz, parks and art galleries. Christiana was always helpful and available to answer any of our questions (including where the best bakery was!). The neighbours were also friendly and helpful. The next time we are in Vienna we will book here!
