Had an amazing stay in Berlin! The neighborhood near the apartment is really cool with a lot of restaurants and bars - definitely recommend Arema, which is just a short walk away - for breakfast or lunch.
Though we did love the area around the flat, the location is a bit farther out from the centre area where we did a lot of our touring. That said, the public transport is right across the street so still convenient for getting around and cabs were fairly reasonable.
Marleen was very helpful and I appreciated her prompt communication. The flat was exactly as described and charmingly decorated. Overall was a perfect space for a group of 5 of us on a girls weekend away.
