I stayed 4 nights in this place. Anna couldn't meet me since she was travelling, but left the keys with her lovely neighbor. The appartment is great, can fit 2 people on the bed and many more on the floor. It's on the 5th floor and doesn't have stairs, which wasn't a problem since I wasn't with bulky luggage - but keep that in mind if you are going with heavy stuff. Great conditions, even better location. I was literally 3 minutes away from the TV Tower and could easily catch a bus and even walk to downtown Berlin, saving a lot of money and time with transportation. I would not hesitate to stay there again next time I am in Berlin. You won't regret it!
