We didn't meet Markus as he was away, but the instructions he left us were perfect to find the apartment, and we met his flatmate Michel, later in the evening, who was very nice.
The room is large and the bed is comfortable.
Unfortunately there is no cooling or fan, so it was quite hot when the windows were closed.
The shower is very good, and the bathroom quite large, so good to move around in.
We did not use the kitchen, as we were a little put off by unusual smells in fridge, and old food. Kitchen was a bit untidy, and not so clean, but if you're eating out, it won't bother you. Also if you want a cheap place to stay, this is a great location, close to transport.
If you're staying on a weekend though, there is not a lot going on in the street in the way of restaurants or cafes. Most things are closed.
