We had a great stay in Vienna, the flat is exactly like in the picture. Everything is very clean and new, you can use the dishwasher and all.
The location was perfect a direct train from the airport ( not the expensive one just a regular one) the metro and tram line 2 are a few minutes walk from the flat and take you directly to the city centre. You have closely shops where you can buy food. And 10 min walk to "gasthaus Kopp" where we had amazing Austrian food. Communication with Andreas was very easy and a very friendly lady welcomed us on arrival.
Only one minor thing there is some construction work happening for another month or so and we got woken up very early which when you are on holiday is not so nice. But this was just the perfect place for the holiday in Vienna highly recommended.
