Josef was an excellent and friendly host. When we arrived he gave us great advice for things to do which would give us an "authentic taste" of Vienna. He also gave us a brief history of the city and an overview of what we could expect. The description of the apartment was accurate and i found it quite cool that Josef built the apartment himself and that is was eco-friendly. The apartment is quite small and as a result can sometimes get a bit stuffy. During the day this was not much of an issue as you can open the windows. However the apartment is on the ground floor so you can't really leave them open during the night so it can get particularly stuffy. The location is quite close to the city centre and right next to the metro station. We loved the quirky and original design of the apartment too! Overall the apartment is excellent value for money and is a great place to stay especially if you're on a budget!
