I have stayed there for 2 weeks. As Daniel has explained every detail I need to know, it was very easy for me to stay there. Every tool I need (cooking tools, hair dryer etc) was available. Location was also perfect, you can run through Olympiapark, there is a REWE across the street, train station is 3-4 min walk away. I could even go to Mediamarkt by walk and came across another wonderful park on the way there.
Highly recommended!
