We are a couple from Bologna, Italy, and we stayed at Josef's apartment for one week during holiday time. The apartment is cozy, clean, well-equipped, even for longer staying than ours, and is not so far from the city centre. It's close to trams and metro stations. There is a tram stop just around the corner!
Josef was an amazing and welcoming host. He gave us plenty of advice about visiting Vienna and a couple of city maps are available in the apartment.
We spent a great time here! :)
