My experience at Hanna's place far exceeded my expectations. Someone else wrote that staying at Hanna's is like staying with an old friend -- and I completely agree!
She is a lovely host who went above and beyond with making sure my stay at hers was comfortable. She has a ton of recommendations for places to check out in her neighborhood, and would even help me research spots if she was unsure. Her home is spacious, comfortable, warm and super clean.
The neighborhood is very convenient and full of hip stores, great restaurants and places for quick bites as well. She lives right next to a park with a viewpoint that overlooks Berlin, in case you crave some green space during your stay. I would 100% recommend Hanna's to my friends and family. If her place is available during your stay in Berlin, consider yourself lucky!
