Perfect location, close to the center of Vienna, bike rental stations and public transport. Pretty apartment with good layout. Maintenance work is required e.g. kitchen tape was entirely loose and lights plus cabinet in bathroom entry area not functional. Be careful to keep the kitchen sink studded, sewage system is smelly. Shower and toilet have openable windows though which is very helpful. Mario is a considerate host, answering quickly and very supportive. Luggage storage before check-in was possible, too. We had a good time and enjoyed our stay :-)
