Thomas was a great host! He provided great directions to his apartment and local tips that were very useful during our stay. His place was in the center of Vienna's main touristic attractions, very short distance to the train station. He was very quick responding to our comments and questions; and his apartment was very organized, stock with supplies and clean. My only suggestion would be to improve the wireless internet since I was unable to check my emails for work; but I think the overall internet strength in Vienna is not too good. Other than that, Thomas apartment was perfect!
