I stayed in Roman's apartment for one week with two friends, with a third joining us for three days in that time. He wasn't available to welcome us but was very responsive to messages before and throughout our stay.

The apartment was beautifully furnished and fit all of us comfortably, the sofa bed being quite large and the bedroom being roomy. It's on the third floor (fourth for Americans) but there's a convenient elevator down the hall. He has a minibar stocked with coffee, beer, soft drinks, wine, liquor, etc. all at reasonable prices. The stove/oven work great, there's a microwave, and a dishwasher as well, which made our lives easier.

The location was great, just a ~5 minute walk to the U-Bahn stop Zieglergasse, with easy access to the Museums Quartier, Stephansplatz, and any number of connections to trams for further trips.

I can't make any complaints.
