No great luxury, but excellent value for money. Great location, Margarethen is a nice neighbourhood, with restaurants and bars (great ice cream parlour just around the corner). City center and Naschmarkt walkable distance. Nice typical old Vienese building, with an escalator. High ceilings, big windows (on inner courtyard), lots of light. Very calm, no street noise. Good beds, kitchen could be a bit better equipped (no working coffee machine, but a percolator), but everything you need is there. Bathroom is small but nice. There is a bath. Very friendly hosts, 2 Hungarian professional classical/jazz musicians who teach at the music academy in Vienna. They were very friendly and helpful. They speak English well (and German). We stayed there with 4 people, 2 adults an 2 teenagers, for 5 days. Suited our purpose very well, would go back there next time we visit Vienna.
