I stayed with Irma for about a month while I was in Vienna for an internship. I had an excellent expirence and highly reccomend it. I will point out that the kitchen is quite small and advise guests to plan on eating in the many excellent, hip resturaunts nearly reather than cooking. Also, don't forget about the private rooftop deck. It has a fantastic view and should bot be missed. The location is outside of the city center but is in Neubau, a lively, culturally vibrant district away from the hordes of tourists. Overall, an excellent stay.
