I stayed at the flat for my first couple of weeks in Berlin and it was perfect - trendy area with lots of coffee shops, bars and restaurants nearby as well as a selection of supermarkets. It's also well-connected to public transport lines to get you in main parts of the city but you can also get around quite a bit by foot! As for the flat, it was clean, comfy and well-equipped. My communication with Valeria was super easy. Would definitely recommend for long and short term stays!
