Avi's place is fabulous. The decor is carefully chosen from vintage items, the bed is comfortable, Avi even provides a suitcase of things you might need on your stay (iron, hairdryer, headphones). Also, if you love dogs, there's Charlie - the best dog in the world (TM) who loved cuddles and is friendly and sweet. The location is great for getting to everywhere else and the atmosphere is so relaxed - you genuinely feel at home. I can't recommend Avi's place enough for a stay in Berlin.
