Dan's apartment is perfectly located in the heart of Vienna and is easily accessible which we really enjoyed. The communication with Dan went really smooth.
Although the apartment isn't very spacious it was perfectly fine for the four of us, especially the bathroom was very comfortable and the bed and sleeping couch were good as well.
The only thing we had a problem with was having dinner with four people because the pans were small and there wasn't enough tableware and cutlery for all of us.
