We visited Munich and stayed in this place in May. Location is very easily accessible by Tram 16, 17 where it takes us to subway stations. The room is good for 3 of us. Toilet is clean and shower water is very strong and hot :).
Room is very neatly organized. It has a washing machine but no dryer, so you'd have hang the cloths in the balcany to dry it.
Although I couldn't smell anything, but my friend smells strong smoke scent in the room and bothers him.
For some reason, I have some allergy symptoms sleeping in the room. I started to get runny nose. I do have a very sensitive nose reactions.

I would recommend this place to people who can take on some smells and dust. Other than these 2 issues, I find it comfortable to stay in there.

one last thing. Renata doesn't know how to speak English. Make sure you have translator or someone who could help you when confirming by phone.
