I stayed here during Oktoberfest weekend and found the place exactly as advertised. They are a friendly couple that gave me good advice on food and German. They speak perfect English German and Russian.
The neighborhood is convenient (Munich has amazing public transport) and considered the nicest part of Munich so you can get to most relevant places within 15 minutes. The room is nice.
Nitpicky things if important to you: Private bathroom but shared shower.
Bed a tiny bit lumpy on one side but large and the room is quiet so I slept like at home.
Obviously I didn’t mind.
