The location was perfect, only couple of minutes walk to the nearest metro station and Vienna is easily explored by metro. Although we didn't get to meet during my stay but Michael offered detailed instruction on how to get to the apartment via public transportation or taxi, so it hardly took me any time to find the right route.
The entire apartment was devided into 3 sections with individual bathroom, the section that I rent was very spaciouus, all the furnitures were warm and clean, all the kitchen utensils were prepared including coffee machine. There was even a flea market at the square before the metro station during the weekend, very interesting. I enjoyed the stay at Michael's apartment and Vienna very much.
