I had a very enjoyable stay at Erhard's place. Erhard is a very polite, nice and helpful host. I felt like a guest, not like a customer. His apparement has a great location, close to the subway and next to a bus stop. The room was big and comfortable. Free coffee and wifi were a big plus. Both Check in and check out were fast and easy; Erhard even allowed me to let my bag at his place after I checked out of my room thus I was able to enjoy another full day at Munich.
The only negative thing I can say that during both nights I spent I woke up to sirens, the windows face towards the street and don't absorb much sound.

However taking all these things into account I would give Erhard's place 5 out of 5 points.

Definitely a big recommendation!
At the cheap cost you won't find anything compareable!
