Michaela's flat was lovely, perfect for a short stay and getting around the city. The flat was very close to Hauptbahnhof (the main Railway station), which is also a great plus. The flat itself was very clean, we had enough bedsheets and towels. Although we didn't get a chance to meet Michaela herself, Mrs Petrovic who showed us around was very nice.
Overall, the stay was very pleasant and we had a great time in Vienna. Highly recommend!
