I have stayed in Peter’s house for three weeks (2+1 but I did not leave any comments for the 1 week part). Therefore, I would like to leave a long and detailed comment.
First of all, Peter and his friend were very nice and friendly people. Most of the time they are at home and more or less living in the kitchen :) Therefore, you always see them and they always greet you with a warm and sincere “hello”. If you are a people person, this room is definitely a very good choice for you.
Secondly, Peter has a dog (probably you have seen on the pictures), Lula. She is a very nice dog. A calm and kind dog. But if you are afraid of dogs, just keep this in your mind this :) However, I still assure you that you will have no problems with the dog.
Then let us continue with other concerns of the people:
Location: Definitely one of the best locations in Munich. You have access to tram + busses going to the city center and you can also use the metro if you just a little bit walk. Moreover, you may not want to use mass transportation in case it is summer since the location is already very close to most of the important places. Just walk and sightsee! By the way, it is very very close to TUM main campus (for those who are students).
The shower is good but be very careful because you need to wait sometime after someone uses the shower due to the heater. I mean just don’t take very long showers otherwise you may have to finish your shower with cold water. For me, it was enough but I also ended up using the all warm water most of the time. So just keep your showers not very long.
The house was very very clean.
Internet was also okay nice broadband speed. I had no connection issues.
For people coming in winter, there is a small heater in the room. So it is not very warm. However, I generally like cold weather and did not have any problems. Maybe they fix the actual heater until next winter, you should ask. However, I was OK, probably you should also be fine.
In the description, it says there is a breakfast. Peter does his best to offer coffee, some bread, jam and other food he shares. However, I was always in a rush; therefore, most of the time I skipped breakfasts.
Lastly, there are 5 stairs no elevators. It was a nice warm-up for me to start to the day :)
In conclusion, my impression is fairly good. Friendly people, good location, clean house with internet. What else would one want :)
