Location: About as central as you can be and not more than a couple of hundred meters away from the U-bahn and closer still for resteraunts, shops, life, Stephansdome...... So do expect it on one or two nights in the week to get a little ruckus - but nothing to really complain about. Apartment we found as advertised the photo's where spot on
One word of caution. Do use shoes on the balcony/terrace.
