Everything others have said about this apartment is true. It's location is spot on, we walked easily to the majority of the tourist attractions from the apartment. The apartment itself was spotless, warm and extremely quiet which was great bearing in mind it's location. The area has a really relaxed vibe and was a great setting for shops ( both local and upmarket), bars and restaurants and there is a market 2 minutes away on a Thursday and Saturday. Although I didn't see our hosts they answered everything I asked promptly by email/text and I felt very comfortable that if I needed anything on my trip they would sort out for me straight away. If I go back to Berlin I would definitely stay in the same apartment.
