The flat is great! Super clean and lots of room, we travelled as a pair and would be comfortable for 3-4 without issue. The apartment had everything we needed and we cooked meals in the flat as well as going out. The apartment is right next to a tram line which is great for getting into Vienna and down to Schonbrunn palace for a lovely day out! We stayed during 35+ degree weather and although warm, were pretty comfortable while inside. All the windows open up to make use of any breeze etc. We really enjoyed our stay.
