It took us about 10-15 minutes to get there with the U1 and U4 metro from the main railway station, and then a 5 minute walk to his place. Dominik was very nice and was there to meet us when we arrived, he quickly showed us the basic things about the house and he spoke good English. The room was nice and simple and there was a fan there so it wasn't too warm at night. We checked out 11 in the morning and everything was very nice.
