This small quiet ground floor flat was perfect for our needs. We were attending a United Nations conference at the Vienna international Centre, which is only about ten minutes on the direct and frequent U1 subway from Schwedenplatz which is about five minutes walk across the canal from the flat. We enjoyed being able to cook some small meals in the flat (note no oven) but also walking the five minutes into the old centre of Vienna to explore local restaurants, cafes and architecture.
Two small supermarkets nearby (one of them very trendily organic).
Don't miss watching the exercises at the Spanish Riding School http://en.wikipedia.org/wiki/Spanish_Riding_School
