Natascha's apartment was a really good and comfortable base from which to explore Vienna. It is 5mins walk from the metro and a whole series of decent shops. The welcome book provided by Natascha also had some great restaurant recommendations, and the apartment had some really nice finishing touches that made it more homely. Check in was also very easy and the response rate/communication/guidance on how to get to the flat from the airport was very simple. The bed was moderately comfortable (a bit squeaky) and we hadn't realised from the pictures that it was a studio flat.
