I stayed in the shared dorm on 3 separate days when I used Munich as a base for my trip. Guess this place is more suited for youths and travelers who need a convenient location to crash for the night.
Location & price wise, you can't ask for more. It's less than 5 minutes to the main train station which makes things very convenient. It's also a 15min walk to Marienplatz.
The staff at reception were rather helpful despite having to attend to numerous travelers who checked in at all hours of the day.
Beds were generally clean since you are given fresh linen upon check-in. The cleanliness of your room(& bathroom) is then dependent on the roommates you get.
The noise level is something one has to be mentally prepared about. I'm not a light sleeper but on 1 of the nights (Sat), the younger guests chilled out at the bar til 2am and made a lot of noise. Thankfully, I had to wake up at 6am-ish to catch a bus to my next destination hence it "helped" me in a way.More
