Fritz's apartment is a basic but cosy room. It's in a perfect location for Oktoberfest, about 5-10 minutes walk from the site. Fritz is an easy going guy and always willing to have a chat. He also let my girlfriends sister stay when she wasn't a listed guest. However, at times we felt there was room for improvement. Such as courtesy with noise past 11pm, when he had loud music playing and friends over, or some confusions about privacy when we felt that it wasn't being respected. We raised these concerns with Fritz and he was very understanding.
Overall, if you are after a fun time or something close to Oktoberfest, this place would work for you.
