We enjoyed our stay at Michael's flat. It was cozy and comfortable. We had everything that we needed there. We particularly loved the location. It was really close to Naschmarkt and there are also some fun and delicious restaurants nearby. We are very happy that we did not choose to stay in the Ringstrasse area because it was packed with tourists and fancy shops. We much prefer being in a Vienesse neighborhood with locals rather than tourists. Michael has a lockbox system so you do not need to meet him at the apartment. That makes it easy because you do not have to worry about your arrival time. We found the system easy to use and navigate and we appreciated that freedom. When we did have some questions he was easy to contact and responded quickly.
