Peters place is just as advertised. In fact, the pictures do not do his place justice, it's fantastic! My friends and I stayed there during Oktoberfest and we couldn't have asked for anything better. The location was perfect, the space in the apartment allowed us to spread out and it was close to mass transit and restaurants/pubs. The flight of 8 sets of stairs was not an issue for any of us and it was very quiet.
The next time I am in Munich with extra people, I hope I am fortunate enough to stay at Peters apartment again!
