Madhiaz is a excellent host. He is ready to help and provide everything that you need. We did not had any problems communicate with him as his response rate was actually quick and to the point. The house is located in an excellent location; only 1 minute walk from an underground line which can connect you to the rest lines and then city center. House it self is an art piece! He transformed it into a small world; words do not make it justice. If you are looking for a place in Vienna, with an amazing host and a cool environment, this is the place! I would definitely recommend! :)
