We had a lovely experience at Robert s appartment. Easy to reach with the Airport Shuttle Bus which will leave you at Westbahnhof station. You would just need to walk a few minutes to reach this huge appartment. All essential elements are in there. Robert was the perfect host, allowing to check in earlier due to our flight cancellation. For that much appreciated. Metro line is at 4 min walk from Robert s place which will give you access to all high spots of Vienna. Great place which will cost you less than the historical centre with a tasteful environment and space.
