I have arrived in Vienna for 3 months for studies. Unfortunatelly, my experience was not on the top in Michael's appartment. I had lots of negative moments to mention. When I arrived, it was very dirty in flat and I should spend time for cleaning it(at night, even I have paid 30 euros for cleaning). On the next day the single lamp above the kitchen broke up, when I tried to swich it on. Also, there were some problems with heating, which was not very nice in cold winter months. Then I had problems with wifi. And used to restart the wifi-box for mobile internet, that Michael provided me, 10 times per day to make it work.
I have paid for this flat approximately 800 euro per months, but I was unpleasant surprised that the quality of this flat does not cost that much money.
However, there were a few positive moments.
Communication with Michael and his helpers was on the top level. Michael really tried to help me in any way it is possible.
Also the location of the flat is very convenient, really close to the center.
