The appartment is a newly refurbished old appartment. The refurbishment has been very successful, the appartment felt modern, convenient and comfortable. It also felt quite safe, should that be a concern. The appartment is quite spacious for two.
Praterstern, is a train station ca 200m from the appartment. This station connects regular trains and the subway, meaning everything from the airport connection to the intra city connections are extremely close and convenient.
There is a variety of stores close by for buying supplies and groceries.
The Viennese tivoli/park is also very close, if you enjoy evening walks with some life around it is a nice alternative.
Not one single complaint, misshap or kerfuffle at all. The hosting, appartment and experience over all was as near perfect as I care to experience. Now I need to go back to Austria.
