Nina's house is located in a great area of Vienna, it is very cool and safe. The only problem was that it was a house that allowed smoking, and that meant for non-smokers (me) it didn't smell great, so that's worth noting.
The house has a lot of space and endless amenities, which are of an excellent quality.
We did struggle with the blinds, unfortunately the woman hosting on Nina's behalf wasn't able to explain this to us via text message.
We also followed Nina's advice to get a taxi from the airport, as it would only be 35 euros, it was more than 50 euro so would definitely go via public transport or uber route.
Would highly suggest providing an updated list of local cafes etc as it's really a great neighborhood.
