I spent 8 nights in Davide's wonderful apartment. It's the perfect compromise between the sociability of a hostel and the privacy of a hotel. I would highly recommend staying to anyone who wants a less sterile experience - and to get a real feel for how it might be to live in Berlin. Davide is a wonderful, warm and accommodating host who made my stay very enjoyable!
A note for anyone who has a disability or is not physially fit - there is no lift and A LOT of stairs.
Thanks and all the best Davide!
