I stayed for 2 weeks at Hannes place. Communication with Hannes was prompt and he was very kind to come get me at the Wien Mitte station without my asking, helped me with my luggage and walked me to the apartment. Despite being a fairly new host to this apartment, Hannes was geniunely very helpful. As i am a yogi, I practice yoga almost daily even when i travel so when i did that at Hannes place i saw some dust at places where most people may not notice! I told Hannes about it and not only was he apologetic, he came the next day and gave the whole place a good clean up personally because he didnt want to delay and couldnt get a cleaner last minute! He also brought a fan and changed the bedsheets to a cooler one due to the unusal hot spring weather this year. My overall experience has been great! You may want to note that there is some works going on in the building right next door. If you are out most of the day, then it is not a problem at all. Even on days when i was around in the day time, it didnt pose a big problem to me.
