A great Place to stay. Staying on the fourth floor might not sound so great at first, but there is an elevator. We stayed there during a heat wave, and between being so high up and the windows at both ends, there was always a pleasant breeze.
The immediate neighborhood is quiet enough to sleep with open windows, but everything from supermarkets and ice cream places to bakeries and restaurants is just around the corner. The center of Vienna is within walking distance (30 min, but through interesting neighborhoods from hipster to shopping district. It is also quite easy to get on public transportation. When we go back to Vienna, we will certainly try to stay at Umberto’s place again
