I would like to start with gratitude to our host that they were understanding and willing to change their house rules a bit to accommodate our stay. Thank you!
The apartment itself is located in a nice building with high ceiling and spacious bedroom.
It was also very warm.
The location of the apartment is good in terms of supermarkets, market, tram and bus stops (public transport in Vienna is very nice to use). The only downside may be that it faces quite a busy crossroad and a train line. Still, with windows closed the noise will not bother you.
The kitchen is small but we were able to cook inside.
All in all - it is a good place to stay
