Fritz' place is right off the grounds of the Wiesn, thus making it an ideal spot during Oktoberfest season. The proximity to the U bahn allowed for a quick 5 minute ride into the old City, making it a great quiet stay during the rest of the year. A good Döner stand just down the street makes this location ideal if you get the evening munchies.
As far as the actual apartment goes, it is a 4 story walk up, so be prepared, but I wouldn't expect anything else from a timeless German apartment building. The apartment is cozy with a wonderful living room and spacious bedroom, as well as a great balcony from which to have a drink or coffee in the morning.
Fritz was a very jovial person and was kind enough to allow a long time friend to stay with us on his couch during Oktoberfest at the last minute. He made check-in a breeze, giving step by step directions on how to find the place as well as key access.
All in all, an excellent stay which we would gladly repeat.
