Philipp is such a nice guy and very warm hearted. I arrived when he is outing, he left the key and told me very detailed how to get it and use it. And his brother, Wenzil also helped me a lot. I'm appreciate to stay in Philipp's apartment and the location is very very convenient to whom will take public transport in Vienna.
The room Philipp provided is bigger than I expected. It's simple and clean. And it is in a beautiful building which surprised me a lot.
I highly recommend here.
Tips: If you require a lot on facility, ask him in advance to make sure you feel comfortable. for example, there is no hair dryer in his house.
