We spent two nights in a standard room and we really enjoyed our stay. We loved the whole green idea, sustainable bathroom in the room and healthy breakfast. One nice getleman even made us a fresh coffee every morning. The service was amazing, everyone was welcoming and helpful. It was also easy to get to the city centre from the hotel. It takes about 15 minutes to het to the Mariahilferstraße and then you can simply walk to the museums district. It is a 20 mins walk to the Schönbrünn palace as well. The buses and trams go everywhere, so it is easy to get to places. Public transport is cheap - about 2,4€/right/person. A cab to a bar/restaurant through a driving app costs about 10€, so both variants are cheap. More pluses - the hotel is located on a quiet street, so there was zero noise at night and it has a beautiful garden around the dining room :) If we are visiting Vienna again, we would surely stay in this hotel! :)
