Thomas was really friendly and cooperative and let us check in especially early as we wanted to go to Oktoberfest, which really helped us out. He is very relaxed and it made us feel at home at his place. Apart from when he showed us in, we didn't see each other much as we had our own key to come and go as we pleased.
The room has plenty of space, we are three 18 year old guys and had enough room with the matress on the floor. The double bed is up on the raised platform and the steps up to this seemed a bit dodgy, but were good enough. I would avoid staying if you are unable to climb a ladder.
The beds were super comfy and really gave us a good nights sleep.
The apartment is near to Isator subway station, and so only a few minutes walk from the main attractions in Munich.
The local area was pleasant and seemed very safe.
I would stay here again!
