We had the opportunity to meet with Franz when we checked in. He is a very friendly and pleasant host. He even placed a bottle of wine to welcome us.
The house is very cozy and only 4 minutes walk to the metro which connects to the different parts of Vienna. Getting to the different places of interest is very convenient. The house has good heating as well as thermostatic mixer tap which is good when taking showers during cold winters. There is a supermarket just within a few minutes walk from the house. I would recommend his house to anyone visiting Vienna.
